• createBlob

  java.sql.Blob createBlob()
                           throws GSException

  Creates a Blob to store a large size of binary data for a Container.

  The created Blob can be used as a Row field. First, set binary data in the Blob using Blob.setBinaryStream(long) etc. and then store it in Container using put(Object) etc.

  At least the following methods can be called on the Blob obtained by this method.

  • Blob.length()
  • Blob.setBinaryStream(long)
  • Blob.setBytes(long, byte[])
  • Blob.setBytes(long, byte[], int, int)
  • Blob.free()

  You do not have to use the Blob created by this method as BLOB to be set on a Row object. You can set an instance of other class implementing Blob, such as SerialBlob. The created Blob does not have any validity period.

  In the current version, since the entire Row is cached in memory, it might be impossible to store larger data than the maximum VM memory size.

  GSException will not be thrown in the current version.

  Throws:

  GSException

• createIndex

  void createIndex(IndexInfo info)
                   throws GSException

  Create an index according to the contents set in IndexInfo.

  For the column of the index to be created, at least one of the column name sequence and column number sequence must be set, and the actual column must be set in the corresponding container. If both are set, corresponding columns and its order must match each other.

  If the index type is not set or IndexType.DEFAULT is set, the default index type is selected according to the criteria described below.

  If an index name is set, a new index is created only if there is no index with the same name or the different name only in upper- or lowercase letters in the target container. See the GridDB Technical Reference for the details. In defining an index name, there are limits on the allowed characters and the length. In the operations of index, the names are not case-sensitive unless otherwise noted.

  If a name index gets duplicated, you must specify the same setting IndexInfo that satisfies the conditions described below, in which case no new index will be created. On the other hand, you can not specify an existing IndexInfo that has the same name as an index with a different name or an unnamed index.

  If an index name is not set, it is assumed that creation of an unnamed index was requested. If an identical index already exists (excluding name), it must be an unnamed index, which in this case no new index will be created.

  In the current version, an index created through Container is considered to be the same set of indexes except for index names if the following conditions are satisfied.

  • The columns to be indexed must match, including its order. Differences in column specification methods, such as column name sequence, column number sequence and single column are ignored.
  • The index types must match. Differences in the specification method of index type such as existence of default designation are ignored.

  In the current version, for the Container instance generated based on (), the following index type is selected as default based on the type of container, the type of corresponding column, etc.

  Column type	collection	time series
  STRING	IndexType.TREE	IndexType.TREE
  BOOL	IndexType.TREE	IndexType.TREE
  NUMERAL	IndexType.TREE	IndexType.TREE
  TIMESTAMP	IndexType.TREE	IndexType.TREE Note:restriction applies
  GEOMETRY	IndexType.SPATIAL	(-)
  BLOB	(-)	(-)
  ARRAY	(-)	(-)

  An Index cannot be set for Time Series Row Keys (TIMESTAMP type). These index types cannot be selected if the default type differs depending on the column type that configures the column.

  If this Container instance holds an uncommitted transaction, commit before create. Container to be processed. If there are other transactions being executed at the same time, wait for them to finish before creating. If an index already exists and no new index is created, it is undefined whether to wait by another transaction. In this case, it is undefined whether uncommitted transactions held by this Container instance are always committed or not.

  In the current version, in the case of satisfying the conditions such as the size of the container, during creating an index, the reference of the container information, a part of the index operations, the trigger operations, and the row operations (including the update of rows) may be performed. Under the definition of Container, other operations may be waited. For the operations during the index creation, the container information doesn't include the index information to be created.

  Throws:

  GSException - When the column or index name to be created does not conform to the above rule

  GSException - If this process's timeout, deletion of this container or schema change, connection failure occurs, or when called after closing

  GSException - When an unsupported index type is specified in the specified column

  java.lang.NullPointerException - when null is specified as argument

  Since:

  3.5

• createIndex

  void createIndex(java.lang.String columnName)
                   throws GSException

  Creates an unnamed index with default type for the column with the specified name.

  Behaves the same as calling createIndex(IndexInfo) with IndexInfo with only the column name set.

  Throws:

  GSException - If the specified column name does not conform to the rule of createIndex(IndexInfo)

  GSException - if a timeout occurs during this operation, this Container is deleted, its schema is changed or a connection failure occurs; or if called after the connection is closed.

  GSException - if indexing is not supported on the specified Column.

  Creates an unnamed index with the specified type for the column with the specified name.

  Behaves the same as calling createIndex(IndexInfo) with IndexInfo with only the column name and type set.

  Throws:

  GSException - If the specified column name and type does not conform to the rule of createIndex(IndexInfo)

  GSException - if a timeout occurs during this operation, this Container is deleted, its schema is changed or a connection failure occurs; or if called after the connection is closed.

  GSException - if the specified type of index is not supported on the specified Column type.

  java.lang.NullPointerException - if a null parameter(s) is specified.

• createRow

  R createRow()
              throws GSException

  Create a new Row object based on the column layout of this Container.

  If the Row object type of the Container is Row, a fixed default value is set in each field of the Row to be created, similar to the case when it is created using a GridStore.createRow(ContainerInfo). In this case, the operation on the created Row also does not affect whether this Container object is closed or not.

  Throws:

  GSException - If an exclusion is sent out when creating a user-defined Row object

  GSException - If invoked after being closed

• createTrigger

  void createTrigger(TriggerInfo info)
                     throws GSException

  Set the trigger.

  If a update operation of a specific type is carried out on this Container, a notification will be sent to the specified URI. If a trigger with the same name as the specified trigger exists, the setting will be overwritten.

  Refer to the definition of TriggerInfo for the detailed trigger settings. The details of the trigger name, the trigger type, notification conditions, notification destination URI and notification contents are as shown below.

  Trigger name

  Multiple trigger names which are identified as the same, including the names only different in ASCII uppercase and lowercase characters, even if they have different types or notification conditions, in a container cannot be defined. And there are the limitations, the allowed characters and the length, on the trigger names. See the GridDB Technical Reference for the details. Trigger names are case-sensitive unless otherwise noted.

  Trigger type

  The following trigger types are supported.

  name	description
  REST	Trigger to notify the specified URI with a REST notification (HTTP POST method) when an update operation of the specified type is carried out on a Container.
  Java Message Service(JMS)	Trigger to send a JMS message to the JMS server of the specified URI when an update operation of the specified type is carried out on a Container. Apache ActiveMQ is used as the JMS provider.

  Notification condition

  Create new Row/ update Row for this Container (put(Object), put(Object, Object), put(java.util.Collection), GridStore.multiPut(java.util.Map), RowSet.update(Object)), delete (remove(Object), RowSet.remove()) Perform notification immediately after executing operation command. If multiple operations are specified as monitoring targets, perform notification after executing any one of these operations.

  Completion of replication at the point notification is carried out is not guaranteed. For notifications corresponding to a create new Row/ update Row or delete command that has been executed by disabling the auto commit mode, if the transaction is not committed at the point of the notification, or if the transaction is aborted after the notification, it may not be possible to get the data included in the notification at the point the notification is received.

  For batch operations involving multiple Rows, notification is carried out for each Row operation. If there is no response within a specified time even if notification has been sent to the specified URl, time out is performed and it will not be sent again. If a failure occurs in a GridDB cluster, in addition to not sending any notification to support a certain update operation, multiple notifications may be sent.

  Notification destination URI

  A notification destination URI is described in the following format.

   (method name)://(host name):(port number)/(path)

  However, if the trigger type is REST, only http can be specified in the method name.

  Notification contents

  Provide notification of the updated Container name, update operation name, and specified column value of the updated Row data. For the update operation name, use "put" to create a new Row/ update Row and "delete" to delete.

  The notification value shall be the specified column value of the Row data that is newly created immediately after a new Row is created, or updated in an update operation, or before deletion in a delete operation. If the column type is TIMESTAMP, an integer to indicate the time passed in milliseconds starting from 1970-01-01T00:00:00Z is set as the value. If the column type if BLOB, GEOMETRY, or array, a blank character string will be set as the value.

  Notification method - For REST

  JSON character strings such as those shown below are sent with the MIME type application/json.

   {
     "container" : "(container name)",
     "event" : "(update operation name)",
     "row" : {
       "(column name)" : (column data),
       "(column name)" : (column data),
       ...
     }
   }

  Notification method - For JMS

  A javax.jms.TextMessage is sent with the specified destination type and destination name.

  The container name is set by javax.jms.Message#setStringProperty("@container", "(container name)"). The update operation name is set by javax.jms.Message#setStringProperty("@event", "(update operation name)").

  The column value is set with a javax.jms.Message#setXXXProperty("(column name)", (column data)) in accordance with the column type.

  When the column layout is changed by a GridStore.putCollection(String, Class, boolean), GridStore.putTimeSeries(String, Class, TimeSeriesProperties, boolean), etc. in relation to a Container with a set trigger, if a column subject to trigger notification is deleted or if its name is changed, the corresponding column will be deleted from the trigger notification targets.

  If the server does not respond to a request sent to the notification destination URI that has been set up when sending a notification from GridDB, standby processing will occur until the process times out. This standby process becomes a cause for the delay in serving notification of an update in the Container as well as some other containers. Therefore, a trigger having an invalid notification destination URI is recommended to be deleted by using dropTrigger(String).

  See the GridDB Technical Reference for the maximum number of triggers that can be set for a single Container and the upper limit of the values for various trigger settings.

  Parameters:

  info - Trigger information of the setting target

  Throws:

  GSException - If the trigger name is null, blank, or does not follow to other rules

  GSException - If the update operation subject to monitoring is not specified

  GSException - If the notification destination URI does not conform to the stipulated syntax

  GSException - If the JMS is specified by the trigger type, and the JMS destination type is null, or is blank, or does not conform to the specified format

  GSException - If the JMS is specified by the trigger type, and the JMS destination name is null, or is blank

  GSException - If the JMS is specified by the trigger type, and the JMS destination name is null, or is blank

  java.lang.NullPointerException - If null is specified in the argument

• dropIndex

  void dropIndex(IndexInfo info)
                 throws GSException

  Delete all indexes that match the content set in IndexInfo.

  The setting information of IndexInfo are used as a condition to narrow down the index to be deleted. Filtering conditions are classified into three categories: column sequence, index type, and index name. Setting each of them is optional. If none of them are set, all created indexes are deleted.

  If a column name sequence or column number sequence is set, it must exist in the corresponding container. If both column name sequence and column number sequence are set, corresponding columns must match each other. If neither the column name sequence nor the column number sequence is set, the index for any column sequence that satisfies other refinement conditions (index type, index name) will be deleted.

  When the index type is set, only the index of the specified type will be deleted. If IndexType.DEFAULT is set, the default type index is selected according to the standard of createIndex(IndexInfo). Columns that do not support indexes and columns that do not support indexes of the specified type are not eligible for deletion. If the index type is not set, index that fulfil the conditions (column sequence, index name) will be deleted.

  If an index name is set, only the index with the specified name will be deleted. The identity of the index name follows the criteria of createIndex(IndexInfo). If an index name is not set, an index with an arbitrary name and an unnamed index that fulfils the conditions (column sequence, index type) will be deleted.

  If there is no index to be deleted, the index will not get deleted.

  Transaction handling is similar to createIndex(IndexInfo). Also, it is undefined whether or not other transactions may be executed while only a few indexes are deleted when multiple indexes are subject to deletion.

  The immediate state after completion of the index deletion request is similar to GridStore.dropContainer(String).

  Throws:

  GSException - if the column or index name to be deleted does not conform to the above rule

  GSException - if the process is timeout, deletion of this container or schema change, connection failure occurs, or called after closing

  java.lang.NullPointerException - when null is specified as argument

  Since:

  3.5

• dropIndex

  void dropIndex(java.lang.String columnName)
                 throws GSException

  Delete only the default type index from the column with the specified name.

  Behaves the same as calling dropIndex(IndexInfo) with IndexInfo with column name and default type set.

  Throws:

  GSException - When the specified column name does not conform to the rule of dropIndex(IndexInfo)

  GSException - if a timeout occurs during this operation, this Container is deleted, its schema is changed or a connection failure occurs; or if called after the connection is closed.

  java.lang.NullPointerException - if a null parameter is specified.

• dropIndex

  void dropIndex(java.lang.String columnName,
               IndexType type)
                 throws GSException

  Deletes only the index of the specified type from the column with the specified name.

  Behaves the same as calling dropIndex(IndexInfo) with IndexInfo with column name and type set.

  Throws:

  GSException - when the specified column name does not conform to the rule of dropIndex(IndexInfo)

  GSException - if a timeout occurs during this operation, this Container is deleted, its schema is changed or a connection failure occurs; or if called after the connection is closed.

  java.lang.NullPointerException - if null is specified as more than one parameter.

• dropTrigger

  void dropTrigger(java.lang.String name)
                   throws GSException

  Nothing is changed if the trigger of the specified name does not exist.

  Throws:

  GSException - If this process times out, this Container is deleted, a connection failure were to occur, or if it is invoked after being closed

  java.lang.NullPointerException - If null is specified in the argument

• flush

  void flush()
             throws GSException

  Writes the results of earlier updates to a non-volatile storage medium, such as SSD, so as to prevent the data from being lost even if all cluster nodes stop suddenly.

  It can be used for operations requiring higher reliability than normal. However, frequent execution of this would cause degradation in response time.

  Its behaviors vary, such as the scope of cluster nodes concerned, depending on the configuration of GridDB.

  Throws:

  GSException - if a timeout occurs during this operation, this Container is deleted or a connection failure occurs; or if called after the connection is closed.

• get

  R get(K key)
        throws GSException

  Returns the content of a Row corresponding to the specified Row key.

  It behaves in the same way as get(Object, boolean) called without requesting a lock for update.

  Throws:

  GSException

  See Also:

• get

  R get(K key,
      boolean forUpdate)
        throws GSException

  Returns the content of a Row corresponding to the specified Row key according to the specified option.

  It can be used only if a Column exists which corresponds to the specified Row key.

  If it requests a lock for update in the manual commit mode, it will hold the lock until a relevant transaction completes or a timeout occurs. The update or deletion operation by any other transaction on the locked Row will wait until the transaction completes or a timeout occurs. The lock will be held even if the target Row is deleted.

  In the autocommit mode, it cannot request a lock for update.

  Parameters:

  forUpdate - indicates whether it requests a lock for update.

  Returns:

  A target Row object. null if no target Row exists.

  Throws:

  GSException - if no Column exists which corresponds to the specified Row key.

  GSException - if it requests a lock for update in the autocommit mode.

  GSException - if a timeout occurs during this operation or the transaction, this Container is deleted, its schema is changed or a connection failure occurs; or if called after the connection is closed; or if an unsupported value is specified as key.

  java.lang.ClassCastException - if the specified Row key does not match the type of a Row key used in mapping operation.

  java.lang.NullPointerException - if null is specified as key.

• getBindType

  Container.BindType<K,R,? extends Container<K,R>> getBindType()
                                                               throws GSException

  Returns the type information associated with this object.

  The type information obtained is set to be the same as the Row key type and Row object type specified when the object was configured.

  The type of Container or its subinterface is not necessarily the same as the type specified at the time of configuration; the type obtained may be that of the subinterface. Furthermore, a one-to-one correspondence with the container type represented by ContainerType is not guaranteed.

  Returns:

  Type information associated with this object

  Throws:

  GSException - If invoked after being closed

  Since:

  Throws:

  GSException - If invoked after being closed

• put

  boolean put(java.util.Collection<R> rowCollection)
              throws GSException

  Based on the specified Row object group, an arbitrary number of Rows will be consolidated to create a new group or updated.

  For each Row in the specified Row object group, a new creation or update operation is carried out just like the case when put(Object) is invoked in accordance with the take-out sequence from the iterator.

  If multiple Rows having the same Row key exist in the specified Row object group, the contents of the rear-most Row having the same Row key will be reflected using the take-out sequence from the iterator of the Row object group as a reference.

  Depending on the Container type and setting, the same restrictions as put(Object) are established for the contents of Rows that can be operated. Refer to definition of the sub-interface for the specific restrictions.

  In the manual commit mode, the target Rows are locked.

  In the auto commit mode, if an exclusion occurs in the midst of processing a Container and its Rows, only the results for some of the Rows in the Container may remain reflected.

  Returns:

  Always false in the current version

  Throws:

  GSException - When an operation violating the restrictions unique to a specific Container type is carried out

  GSException - if a timeout occurs during this operation or the transaction, this Container is deleted, its schema is changed or a connection failure occurs; or if called after the connection is closed; or if an unsupported value is set in the key or the Row object.

  java.lang.ClassCastException - if the specified Row objects does not match the value types of Row objects used in mapping operation, respectively.

  java.lang.NullPointerException - if NULL is specified as rowCollection or its element; As with put(Object, Object), if null is included in a specific part of the row object.

  See Also:

  put(Object)

• put

  boolean put(K key,
            R row)
              throws GSException

  Newly creates or updates a Row, based on the specified Row object and also the Row key specified as needed.

  If a Column exists which corresponds to the specified Row key, it determines whether to newly create or update a Row, based on the Row key and the state of the Container. If there is no corresponding Row in the Container, it determines to newly create a Row; otherwise, it updates a relevant Row. If a Row key is specified besides a Row object, the specified Row key is used in preference to the Row key in the Row object.

  If no Column exists which corresponds to the specified Row key, it always creates a new Row. In such a case, specify null as key.

  Restrictions are applied depending on the type of Container and its settings. See the descriptions of subinterfaces for detailed restrictions.

  In the manual commit mode, the target Row is locked.

  Parameters:

  key - A target Row key

  row - A Row object representing the content of a Row to be newly created or updated.

  Returns:

  TRUE if a Row exists which corresponds to the specified Row key.

  Throws:

  GSException - if a Row key is specified although no Column exists which corresponds to the key.

  GSException - if its operation is contrary to the restrictions specific to a particular Container.

  GSException - if a timeout occurs during this operation or the transaction, this Container is deleted, its schema is changed or a connection failure occurs; or if called after the connection is closed; or if an unsupported value is set in the key or the Row object.

  java.lang.ClassCastException - if the specified key or Row object does not completely match the type(s) used in mapping operation.

  java.lang.NullPointerException - if null is specified as row; For objects in row objects corresponding to row fields, if there is a NOT NULL constrain but null is set, it will in include elements of null when array type is selected.

• put

  boolean put(R row)
              throws GSException

• query

  Query<R> query(java.lang.String tql)
                 throws GSException

  Creates a query object to execute the specified TQL statement.

  It cannot be used for a query whose output format does not match the types of Rows in this Container, such as a query containing an aggregation operation in its selection expression. For such a query, query(String, Class) can be used instead.

  When obtaining a set of Rows using Query.fetch(boolean), the option of locking for update can be enabled only for the queries that will not select Rows which do not exist in this Container. For example, it cannot be enabled for a query containing an interpolation operation.

  In the current version, due to an error in the TQL statement, GSException and by specifying null with an argument that cannot specify null, NullPointerException will not be dispatched. If there is an error in the argument, an exception will be thrown when the resulting query is fetched.

  Parameters:

  tql - TQL statement. null cannot be specified

  Throws:

  GSException - It will not be thrown in the current version.

  See Also:

  java.lang.ClassCastException - if the specified Row key does not match the type of a Row key used in mapping operation.

  java.lang.NullPointerException - if null is specified.

• setAutoCommit

  void setAutoCommit(boolean enabled)
                     throws GSException

  Change the setting of the commit mode.

  In the auto commit mode, the transaction state cannot be controlled directly and change operations are committed sequentially. If the auto commit mode is disabled, i.e. in the manual commit mode, as long as the transaction has not timed out or commit() has been invoked directly, the same transaction will continue to be used in this Container and change operations will not be committed.

  When the autocommit mode is switched from On to Off, uncommitted updates are committed implicitly. Unless the commit mode is changed, the state of the transaction will not be changed. These behaviors are the same as those of Connection.setAutoCommit(boolean).

  Throws:

  GSException - if a timeout occurs during this operation or the transaction, this Container is deleted or a connection failure occurs, when a commit is requested after a mode change; or if called after the connection is closed.

  an array containing the constants of this enum type, in the order they are declared

Enum Constant Detail

• LIMIT

  public static final FetchOption LIMIT

  Used to set the maximum number of Rows to be fetched.

  If the number of Rows in a result exceeds the maximum, the maximum number of Rows counting from the 0-th in RowSet are fetched. The rest of the Rows in the result cannot be fetched.

  The supported types of values are Integer and Long. Negative values are not available. If the setting is omitted, the limit is not defined.

• PARTIAL_EXECUTION

  public static final FetchOption PARTIAL_EXECUTION

  Used to set the partial execution mode.

  In the partial execution mode, it is trying for the buffer size of the intermediate query processing and the data transfer, etc. to fit inside a fixed size by dividing the target data and getting the query results in each divided range. Therefore the results for some data ranges may not be determined when the RowSet is obtained, and in the middle of getting the results, there are the cases that the query is executed partially for the rest of the ranges.

  In this version, the partial execution mode can be used for queries satisfying all the following conditions. And it can be used in combination with LIMIT option. Even if not satisfying the conditions, the error may not be detected when setting the fetch option.

  • The query must be specified by TQL
  • The SELECT clause must be consisted of only '*' and an ORDER BY clause must not be specified.
  • The target Container must have been set to the auto commit mode at the each partial execution of the query.

  In the partial execution mode, rows that can be fetched at the each partial execution of the query based on the separation level and the status of the corresponding Container transaction are used. However rows that don't exist at the first time of the whole query execution may not be reflected to the results.

  For inhibited operations and behaviors on RowSet in this mode, see the individual definitions.

  The only supported type for this setting is Boolean. The value matching to Boolean.TRUE must be specified to activate this mode. In this version, the partial execution mode is not effective unless setting the mode explicitly.

  Since:

  4.0

Method Detail

• getErrorCode

  public int getErrorCode()

  Returns an error number.

  It returns 0 if no corresponding number is found.

• getMessage

  public java.lang.String getMessage()

  Overrides:

  getMessage in class java.lang.Throwable

• getParameters

  public java.util.Map<java.lang.String,java.lang.String> getParameters()

  Returns a map of parameters related to the error.

  It is used to extract particular information about the error. Returned map is a set which each entry consists of a parameter name and a parameter value. For the parameters included in this map, see the definition of interfaces which may output this exception or the definition of related interfaces.

  The information in the map is also included in the message string returned by getMessage() in principle. But by a fixed parsing rule, it may not be able to extract the particular information from this message. Even if the intended information can be extracted from a context in a version, for other conditions, unintended information may be acquired or nothing may be acquired. By using this map, a part of information specified in the definition of the interfaces can be acquired without parsing.

  When recording only the content of the returned map and not recording other exception information such as the message text, it may become difficult to identify the reason for the error.

Method Detail

• equals

  public boolean equals(java.lang.Object obj)

  Indicates whether some other object is "equal to" this one.

  Objects generated by valueOf(String) and have no notation difference except inconsistent spelling such as blank character as a delimiter or the default SRID values are considered to be equivalent even if WKT representation of the source is not equivalent to each other as a string. For example, objects generated with the following three WKT representation are considered to be equivalent.

   POLYGON((0 0,10 0,10 10,0 10,0 0))
   POLYGON( (0 0,10 0,10 10,0 10,0 0) )
   POLYGON((0 0,10 0,10 10,0 10,0 0);-1)

  On the other hand, objects which have no equivalent WKT representation as a string because of the difference in the start/end position to the closed line that make up the area are considered not to be equivalent even if they indicate to the same space region. For example, objects generated with the following two WKT representation are considered not to be equivalent.

   POLYGON((0 0,10 0,10 10,0 10,0 0))
   POLYGON((0 10,0 0,10 0,10 10,0 10))

Method Detail

• close

  void close()
             throws GSException

  Disconnects with GridDB and releases related resources as necessary.

  Even if GSException is thrown, the connection and local resources are released properly. However, the transaction state etc. might remain in GridDB. If the connection is already closed, this method will not work effectively.

  Throws:

  GSException - if a connection failure occurs

• createRow

  Row createRow(ContainerInfo info)
                throws GSException

  Creates a new Row by specifying ContainerInfo.

  Include the ColumnInfo list and Row key configuration so as to conform to the restrictions stipulated in Container. Specify the column layout in ContainerInfo.

  In addition, by including the Container type in ContainerInfo, it can be verified whether the restrictions unique to a specific Container type are conformed to or not. However, the Container type will not be included even if a Row.getSchema() is invoked against the created Row.

  Each field will be set to the initial value which is based on ColumnInfo of each column in the specified ContainerInfo. The initial value corresponding to the return value of ColumnInfo.getDefaultValueNull() is selected by the following way.

  Return value of ColumnInfo.getDefaultValueNull()	Initial value
  true	NULL. However a row which violates constraints can not be created.
  false	The empty value. See the definition of Container.
  null	In the current version, same as false.

  An empty value defined in Container is set as the initial value for each field of the created Row.

  The operation on the created Row also does not affect whether this GridStore object is closed or not.

  Parameters:

  info - Container information including the column layout. Other contents are ignored

  Returns:

  Created Row

  Throws:

  GSException - If the Container type or restrictions of the column layout are not conformed to

  GSException - If invoked after being closed

  If a transaction under execution exists in a Container subject to processing, the system will wait for these to be completed before deleting the data.

  Immediately after the container deletion request is completed, the memory and storage area used for the index or row of the container may not be reused immediately. In addition, when delete processing is run on the cluster, increase in load may occur for sometime.

  Parameters:

  name - Name of a Container subject to processing

  Throws:

  GSException - If this process times out, a connection failure were to occur, or if it is invoked after being closed

• fetchAll

  void fetchAll(java.util.List<? extends Query<?>> queryList)
                throws GSException

  Query execution and fetch is carried out on a specified arbitrary number of Query, with the request unit enlarged as much as possible.

  For each Query included in a specified list, perform a similar query execution and fetch as when Query.fetch() is performed individually and set the RowSet in the results. Use Query.getRowSet() to extract the execution results of each Query. However, unlike the case when carried out individually, the target node is requested for the same storage destination, etc. with a unit that is as large as possible. Based on this, the larger the number of elements in the list, the higher is the possibility that the number of correspondences with the target node will be reduced. Query in a list are not executed in any particular order.

  Only a Query that has not been closed, including corresponding Container acquired via this GridStore object, can be included in a specified list. Like a Query.fetch(), the RowSet formed last and held by each Query will be closed. If the same instance is included multiple times in a list, the behavior will be the same as the case in which the respective instances differ.

  Like other Container or Row operations, consistency between Containers is not guaranteed. Therefore, the processing results for a certain Container may be affected by other operation commands that have been completed prior to the start of the process.

  The commit mode of each Container corresponding to the specified Query can be used in either the auto commit mode or manual commit mode. The transaction status is reflected in the execution results of the query. If the operation is completed normally, the corresponding transaction of each Container will not be aborted so long as the transaction timeout time has not been reached.

  If an exception occurs in the midst of processing each Query, a new RowSet may be set for only some of the Query. In addition, uncommitted transactions of each Query corresponding to the designated Container may be aborted.

  If the system tries to acquire a large number of Rows all at once, the upper limit of the communication buffer size managed by the GridDB node may be reached, possibly resulting in a failure. Refer to "System limiting values" in the GridDB Technical Reference for the upper limit size.

  The thrown GSException may contain container parameter. For the details of the parameters related the error, see the definition of GridStore.

  Parameters:

  queryList - List of Query targeted

  Throws:

  GSException - If a Query other than a Query obtained via this GridStore object is included

  GSException - If the system tries to execute a query containing a wrong parameter, syntax or command. For example, when a column type that is not compatible with the argument of the function is specified in the TQL. Refer to the various definitions of the function to create this query for the specific restrictions

  GSException - If the execution results do not conform to the expected type of each component of the RowSet, when a TQL is executed.

  GSException - If this process or related transaction times out, if the corresponding Container is deleted or the schema is changed, if a connection failure occurs, or if the corresponding Container is invoked after being closed

  java.lang.NullPointerException - If null is specified in the argument queryList, or if null is included as a component the argument queryList

  java.lang.NullPointerException - If a non-permitted null is included in the parameter given when creating this query. To be executed in GridDB The evaluation results of the TQL text will not be sent out

  Get a Collection object whose Rows can be processed using a Row.

  Except for points where the expected Container type is limited to ContainerType.COLLECTION and the returned type is Collection, the behavior will be the same as getContainer(String).

  Returns:

  Corresponding Collection if a Collection exists and null if not.

  Throws:

  GSException - If a TimeSeries with the same name exists

  GSException - If this process times out, a connection failure were to occur, or if it is invoked after being closed

  Excluding the next point, the behavior will be the same as getCollection(String, Class) or getTimeSeries(String, Class).

  • Return a Container object based on the existing Container type and column layout
  • No error accompanying these non-conformances will occur as the Container type and column layout are not specified
  • The Row object type of the Container returned will always be Row

  Parameters:

  name - Name of a Container subject to processing

  Returns:

  Corresponding Container if a Container exists and null if not. If a Container exists and the type is ContainerType.COLLECTION, the instance created will be a Collection instance. If the type is ContainerType.TIME_SERIES, the instance created will be a TimeSeries instance.

  name - Name of a Container subject to processing

  bindType - Type information associated with the container subject to processing

  Returns:

  An instance of the type of the corresponding Container or its subinterfaces

  Throws:

  GSException - if the contents of the name and bindType parameters do not conform to the rules

  GSException - If the specified type is not suitable as the Row object type. Refer to the definition of Container for details.

• getContainerInfo

  ContainerInfo getContainerInfo(java.lang.String name)
                                 throws GSException

  Get information related to a Container with the specified name.

  A name stored in GridDB is set for the Container name to be included in a returned ContainerInfo. Therefore, compared to the specified Container name, the notation of the ASCII uppercase characters and lowercase characters may differ.

  The column sequence is set to Do Not Ignore. This setting can be verified through ContainerInfo.isColumnOrderIgnorable().

  In the current version, whether to use of NULL for the initial value is not set. Note that it may be set in the future version. This information can be acquired through ColumnInfo.getDefaultValueNull() on each column.

  Parameters:

  name - the target Container name

  Returns:

  Container Info of the specific Container.

  Throws:

  GSException - if a timeout occurs during this operation or a connection failure occurs; or if called after the connection is closed.

  java.lang.NullPointerException - if null is specified as the parameter.

• getPartitionController

  PartitionController getPartitionController()
                                             throws GSException

  Get PartitionController on the corresponding GridDB cluster.

  Use is no longer possible once this GridStore is closed.

  Returns:

  PartitionController on the corresponding GridDB cluster

  Throws:

  GSException - If invoked after being closed

                                throws GSException

  Get a TimeSeries object whose Rows can be processed using a Row.

  Except for points where the expected Container type is limited to ContainerType.TIME_SERIES and the returned type is TimeSeries, the behavior will be the same as getTimeSeries(String).

  Returns:

  Corresponding TimeSeries if a TimeSeries exists and null if not.

  Throws:

  GSException - If a Collection with the same name exists

  GSException - If this process times out, a connection failure were to occur, or if it is invoked after being closed

  java.lang.NullPointerException - If null is specified in the argument

  See Also:

  <R> TimeSeries<R> getTimeSeries(java.lang.String name,
                                java.lang.Class<R> rowType)
                              throws GSException

  Returns a TimeSeries object to manipulate a TimeSeries with the specified name.

  For the correspondence between a specified type and a Column layout, see the description of Container.

  Parameters:

  name - Name of TimeSeries subject to processing

  rowType - Type of Row object corresponding to the column layout of the TimeSeries subject to processing

• multiGet

  java.util.Map<java.lang.String,java.util.List<Row>> multiGet(java.util.Map<java.lang.String,? extends RowKeyPredicate<?>> containerPredicateMap)
                                                               throws GSException

  Get an arbitrary number and range of Rows of a Container based on the specified conditions, with the request unit enlarged as much as possible.

  Get the Row contents in accordance with the conditions included in the specified map, similar to invoking Container.get(Object) or Query.fetch() individually. However, unlike the case when carried out individually, the target node is requested for the same storage destination, etc. with a unit that is as large as possible. Based on this, the larger the total number of Rows conforming to the conditions and the larger the total number of target Containers, the higher is the possibility that the number of correspondences with the target node will be reduced.

  A specified map is composed of an arbitrary number of entries that adopt the Container name as the key and the acquisition condition represented by RowKeyPredicate as the value. Multiple instances with the same RowKeyPredicate can also be included. In addition, a subject Container may be a mixture of different Container types and column layouts. However, there are some acquisition conditions that cannot be evaluated due to the composition of the Container. Refer to the definitions of the various setting functions for RowKeyPredicate for the specific restrictions. In addition, the specified Container name must be a real Container. The Container cannot include null as a key or value of the map.

  A returned map is composed of entries that adopt the Container name as its key and list of Row objects as its value. And only the real Container names at the request included in a specified map as acquisition conditions are included in a returned map. If multiple entries in which Container names with different notations in uppercase and lowercase letters that specify the same Container are set are included in a specified map, a single entry consolidating these is stored in the returned map. If multiple Row objects are included in the same list, the stored sequence follows the Container type and the definition of the sub-interface of the corresponding Container. If not a single Row corresponding to the specified Container exists, the list of corresponding Row objects is blank.

  When a returned map or list included in a map is updated, whether an exception will occur or not when UnsupportedOperationException, etc. is executed is still not defined.

  Like other Container or Row operations, consistency between Containers is not guaranteed. Therefore, the processing results for a certain Container may be affected by other operation commands that have been completed prior to the start of the process.

  Like Container.get(Object, boolean) or Query.fetch(boolean), a transaction cannot be maintained and requests for updating locks cannot be made.

  If the system tries to acquire a large number of Rows all at once, the upper limit of the communication buffer size managed by the GridDB node may be reached, possibly resulting in a failure. Refer to "System limiting values" in the GridDB Technical Reference for the upper limit size.

  The thrown GSException may contain container parameter. For the details of the parameters related the error, see the definition of GridStore.

  Parameters:

  containerPredicateMap - Map made up of targeted Container names and conditions

  Returns:

  Map that maintains Row groups conforming to the conditions by Container

  Throws:

  GSException - If acquisition conditions concerning a specified Container that cannot be evaluated are specified

  GSException - If this process or transaction times out, a connection failure were to occur, or if it is invoked after being closed

  java.lang.NullPointerException - If null is specified as an argument containerRowsPredicate, if null is included as a key or value of this map

  Container.get(Object), Query.fetch(), RowKeyPredicate

• multiPut

  void multiPut(java.util.Map<java.lang.String,java.util.List<Row>> containerRowsMap)
                throws GSException

  New creation or update operation is carried out on an arbitrary number of rows of a Container, with the request unit enlarged as much as possible.

  For each Row object included in a specified map, a new creation or update operation is carried out just like the case when Container.put(Object) is invoked individually. However, unlike the case when carried out individually, the target node is requested for the same storage destination, etc. with a unit that is as large as possible. Based on this, the larger the total number of Row objects specified and the larger the total number of target Containers, the higher is the possibility that the number of correspondences with the target node will be reduced.

  A specified map is composed of an arbitrary number of entries that adopt the Container name as its key and list of Row objects as its value. A subject Container may be a mixture of different Container types and column layouts. However, the Containers must already exist. The Container cannot include null as a key or value of the map.

  An arbitrary number of Row with the same column layout as the subject Container can be included in each list of Row objects. In the current version, all the column sequences must also be the same. The Container cannot include null as a component of the list.

  Depending on the Container type and setting, the same restrictions as Container.put(Object) are established for the contents of Rows that can be operated. Refer to the sub-interface definition of Container for the specific restrictions.

  If there are multiple Row objects having the same Row key targeting the same Container in the designated map, the contents of the rear-most Row object having a Row key with the same value will be reflected using the take-out sequence from the iterator of the map entry group as a reference if it is between different lists, or the component sequence of the list as a reference if it is within the same list.

  The transaction cannot be maintained and the lock cannot continue to be retained. However, if the lock that affects the target Row is secured by an existing transaction, the system will continue to wait for all the locks to be released.

  Like other Container or Row operations, consistency between Containers is not guaranteed. Therefore, the processing results for a certain Container may be affected by other operation commands that have been completed prior to the start of the process.

  If an exclusion occurs in the midst of processing a Container and its Rows, only the results for some of the Rows of some of the Containers may remain reflected.

  The thrown GSException may contain container parameter. For the details of the parameters related the error, see the definition of GridStore.

  Parameters:

  containerRowsMap - A map made up of a list of Row objects and target Container names

  Throws:

  GSException - If the target Container does not exist, or if the column layouts of the target Container and Row object do not match

  GSException - When an operation violating the restrictions unique to a specific Container type is carried out

  GSException - If this process or transaction times out, a connection failure were to occur, or if it is invoked after being closed, or if a value outside the supported range is included in the Row object

  java.lang.NullPointerException - If null is specified as an argument containerRowsMap, if null is included as a key or value of this map, or if null is included as a component of the list constituting the map

  Container.put(Object)

• putCollection

  <K,R> Collection<K,R> putCollection(java.lang.String name,
                                    java.lang.Class<R> rowType)
                                throws GSException

  Newly creates or updates a Collection.

  If a Container with the specified name does not exist, it newly creates a Collection based on the Column layout defined by the specified class. If a Container with the specified name already exists and its whole Column layout matches the specified type, it behaves in the same way as getCollection(String, Class), except that it waits for active transactions to complete.

  For the correspondence between a specified type and a Column layout, see the description of Container

  If a Collection with the specified name exists and if a transaction(s) is active in the Collection, it does the operation after waiting for the transaction(s) to complete.

  Parameters:

  name - Name of a Collection subject to processing

  rowType - Type of Row object corresponding to the column layout of the Collection subject to processing

  Returns:

  A Collection object created or updated

  Throws:

  GSException - if a Collection with the specified name exists; or if the Column layout and additional settings conflict with the specified type with regard to the existing TimeSeries with the specified name.

  GSException - if a timeout occurs during this operation or a connection failure occurs; or if called after the connection is closed.

  java.lang.NullPointerException - a null parameter(s) is specified.

• putCollection

  <K,R> Collection<K,R> putCollection(java.lang.String name,
                                    java.lang.Class<R> rowType,
                                    boolean modifiable)
                                throws GSException

  Newly creates or updates a Collection with the specified option.

  If a Container with the specified name does not exist, it newly creates a Collection based on the Column layout defined by the specified class. If a Collection with the specified name already exists and its whole Column layout matches the specified type, it behaves in the same way as getCollection(String, Class), except that it waits for active transactions to complete.

  If modifiable is true and a Collection with the specified name exists, it changes its layout as necessary. When changing the layout, it leaves unchanged the existing Columns with the same name and type as defined by the specified class. If a Column name defined by the class is not found in the existing Collection, it creates a Column with the name; and it deletes other Columns in the existing Collection as well as their data. It fails if a Column with the same name but of a different type exists. It is not possible to create or delete a Column corresponding to a Row key.

  If a trigger is set in a Container, and if a column whose trigger is subject to notification is deleted due to a change in the column layout, the column will be deleted from the list of triggers subject to notification.

  The values of Columns to be newly created are initialized with an empty value defined in Container as an initial value.

  For the correspondence between a specified type and a Column layout, see the description of Container

  If a Collection with the specified name exists and if a transaction(s) is active in the Collection, it does the operation after waiting for the transaction(s) to complete.

  When creating a Collection with Row key, an index of default type of the Row key which is defined by Container.createIndex(String) is created. The index is removable.

  In the current version, when conditions such as the size of a container are met, from the beginning to the end of changing the column layout, it is sometimes possible to refer to the container information for the container to be processed and reference the row without updating lock. There are cases where other operations are made to wait as defined in Container. If another operation is performed during column layout change, the prior layout will be used.

  Parameters:

  name - Name of a Collection subject to processing

  rowType - Type of Row object corresponding to the column layout of the Collection subject to processing

  modifiable - Indicates whether the column layout of the existing Collection can be changed or not

  Returns:

  A Collection object created or updated

  Throws:

  GSException - if a TimeSeries with the same name exists; or if modifiable is false and the Column layout of the existing Collection with the specified name conflicts with the requested layout; or if modifiable is true and it attempted to change the unchangeable items in the existing Collection with the specified name.

  GSException - if the specified type is not proper as a type of a Row object. For more information, see the description of Container.

  GSException - if a timeout occurs during this operation or a connection failure occurs; or if called after the connection is closed.

  java.lang.NullPointerException - if a null parameter(s) is specified.

                                throws GSException

  Creates a new Container or updates a Container by specifying ContainerInfo.

  Excluding the next point, the behavior will be the same as putCollection(String, Class, boolean) or putTimeSeries(String, Class, TimeSeriesProperties, boolean).

  • Use ContainerInfo to specify the Container type, column layout, as well as the TimeSeries composition option where necessary
  • The Row object type of the Container returned will always be Row

  Arguments modifiable with the same respective name are used in the same way as well.

  A list of the methods to specify Container-related information is given below.

  item	argument	description
  Container name	name or info	Specify a value that is not null in at least one of the arguments. A different value must be specified when specifying both sides.
  Container type	info	Specify a value that is not null. If ContainerType.COLLECTION is specified, the behavior will be the same as putCollection(String, Class, boolean). If ContainerType.TIME_SERIES is specified, the behavior will be the same as putTimeSeries(String, Class, TimeSeriesProperties, boolean).
  Column layout	info	Set the ColumnInfo list and Row key configuration so as to conform to the restrictions stipulated in Container. However, in the current version, it is not allowed that the list includes one or more ColumnInfo which returns a value except for null through ColumnInfo.getDefaultValueNull().
  Ignore column sequence	info	If ignored, no verification of the conformance with the column sequence of existing Containers with the same name will be carried out.
  TimeSeries composition option	info	A value that is not null can be specified only if the Container type is ContainerType.TIME_SERIES.
  Index setting	info	Ignored in the current version. In future versions, if settings that do not conform to the rules of Container.createIndex(String, IndexType) are included, an exception may be sent out.
  Trigger setting	info	Ignored in the current version. In future versions, if settings that do not conform to the rules of Container.createTrigger(TriggerInfo) are included, an exception may be sent out.
  Container similarity	info	The specified contents will be reflected if a setting other than null is specified and newly created. The settings of an existing Container cannot be changed. The settings are ignored if null is specified.

                              throws GSException

  Newly creates or updates a TimeSeries.

  If a Container with the specified name does not exist, it newly creates a TimeSeries based on the Column layout defined by the specified class. If a TimeSeries with the specified name already exists and its whole Column layout matches the specified type, it behaves in the same way as getTimeSeries(String, Class), except that it waits for active transactions to complete.

  For the correspondence between a specified type and a Column layout, see the description of Container.

  If a TimeSeries with the specified name exists and if a transaction(s) is active in the TimeSeries, it does the operation after waiting for the transaction(s) to complete.

  Parameters:

  name - Name of TimeSeries subject to processing

  rowType - Type of Row object corresponding to the column layout of the TimeSeries subject to processing

  Returns:

  A TimeSeries object created or updated

  Throws:

  GSException - if a Collection with the same name exists; or if the Column layout and additional settings conflict with the specified type with regard to the existing TimeSeries with the specified name.

                              throws GSException

  Newly creates or updates a TimeSeries with the specified additional settings and update option.

  If a Container with the specified name does not exist, it newly creates a TimeSeries based on the Column layout and additional settings defined by the specified class. If a TimeSeries with the specified name already exists and its whole Column layout and additional settings match the specified type, it behaves in the same way as getTimeSeries(String, Class), except that it waits for active transactions to complete.

  If modifiable is true and a TimeSeries with the specified name exists, it changes its layout as necessary. When changing the layout, it leaves unchanged the existing Columns with the same name and type as defined by the specified class. If a Column name defined by the class is not found in the existing TimeSeries, it creates a Column with the name; and it deletes other Columns in the existing Collection as well as their data. It fails if a Column with the same name but of a different type exists. It is not possible to create or delete a Column corresponding to a Row key or change the options for configuring a TimeSeries. When specifying some options for configuring a TimeSeries, specified values must be the same as the current settings.

  If a trigger is set in a Container, and if a column whose trigger is subject to notification is deleted due to a change in the column layout, the column will be deleted from the list of triggers subject to notification.

  For the initial values for newly created Columns, see the description of putCollection(String, Class, boolean).

  For the correspondence between a specified type and a Column layout, see the description of Container

  If a TimeSeries with the specified name exists and if a transaction(s) is active in the TimeSeries, it does the operation after waiting for the transaction(s) to complete.

  Parameters:

  name - Name of TimeSeries subject to processing

  rowType - Type of Row object corresponding to the column layout of the TimeSeries subject to processing

  props - Composition option of TimeSeries. If null is specified, the existing settings will be inherited if a TimeSeries with the same name exists. If not, they will be deemed as specified in the initial status of TimeSeriesProperties.

  modifiable - To permit a change in the column layout of an existing TimeSeries or not

  Returns:

  A TimeSeries object to created or deleted

  Throws:

  GSException - if a Collection with the same name exists; or if modifiable is false and the Column layout and additional settings conflict with the specified type with regard to the existing TimeSeries with the specified name; or if modifiable is true and it attempted to change the unchangeable items in the existing TimeSeries with the specified name.

  GSException - if the specified type is not proper as a type of a Row object. For more information, see the description of Container.

• putTimeSeries

  TimeSeries<Row> putTimeSeries(java.lang.String name,
                              ContainerInfo info,
                              boolean modifiable)
                                throws GSException

  Creates a new TimeSeries or updates a TimeSeries by specifying ContainerInfo.

  Except for points where the Container type is limited to ContainerType.TIME_SERIES and the returned type is TimeSeries, the behavior will be the same as putContainer(String, ContainerInfo, boolean).

  Parameters:

  name - Name of TimeSeries subject to processing

  info - Information of TimeSeries subject to processing. Specify either null or ContainerType.TIME_SERIES in the Container type

  modifiable - To permit a change in the column layout of an existing TimeSeries or not

  Returns:

  Corresponding TimeSeries

  Throws:

  GSException - If specifications other than the Container type do not conform to the rules of putContainer(String, ContainerInfo, boolean). If the specifications do not conform to the restrictions related to the Container type as well

  GSException - If this process times out, a connection failure were to occur, or if it is invoked after being closed

  java.lang.NullPointerException - If null is specified in the argument info

Method Detail

• close

  public abstract void close()
                      throws GSException

  Closes all GridStore instances created by this Factory and release related resources as necessary.

  Even if GSException is thrown, all related connection resources are released. If the connection is already closed, this method will not work effectively. It is also called when stopping the current VM.

  Specified by:

  close in interface java.io.Closeable

  Specified by:

  close in interface java.lang.AutoCloseable

  Throws:

  GSException - if an connection failure etc. occurs while closing.

• getGridStore

  public abstract GridStore getGridStore(java.util.Properties properties)
                                  throws GSException

  Returns a GridStore with the specified properties.

  When obtaining GridStore, it just searches for the name of a master node (hereafter, a master) administering each Container as necessary, but authentication is not performed. When a client really needs to connect to a node corresponding to each Container, authentication is performed.

  The following properties can be specified. Unsupported property names are ignored.

  Property	Description
  host	A destination host name. An IP address (IPV4 only) is also available. Mandatory for manually setting a master. For autodetection of a master, omit the setting.
  port	A destination port number. A string representing of a number from 0 to 65535. Mandatory for manually setting a master. For autodetection of a master, omit the setting.
  notificationAddress	An IP address (IPV4 only) for receiving a notification used for autodetection of a master. A default address is used if omitted. This property cannot be specified with neither notificationMember nor notificationProvider properties at the same time.
  notificationPort	A port number for receiving a notification used for autodetection of a master. A string representing of a number from 0 to 65535. A default port number is used if omitted.
  clusterName	A cluster name. It is used to verify whether it matches the cluster name assigned to the destination cluster. If it is omitted or an empty string is specified, cluster name verification is not performed.
  database	Name of the database to be connected. If it is omitted, "public" database that all users can access is automatically connected. Users can handle the containers belonging to the connected database.
  user	A user name
  password	A password for user authentication
  consistency	Either one of the following consistency levels: "IMMEDIATE" The updates by other clients are committed immediately after a relevant transaction completes. "EVENTUAL" The updates by other clients may not be committed even after a relevant transaction completes. No update operation cannot be applied to Container. By default, "IMMEDIATE" is selected.
  transactionTimeout	The minimum value of transaction timeout time. The transaction timeout is counted from the beginning of each transaction in a relevant Container. A string representing of a number from 0 to Integer.MAX_VALUE in seconds. The value 0 indicates that it is always uncertain whether a timeout error will occur during a subsequent transaction. If a value specified over the internal upper limit of timeout, timeout will occur at the internal upper limit value. If omitted, the default value used by a destination GridDB is applied.
  failoverTimeout	The minimum value of waiting time until a new destination is found in a failover. A numeric string representing from 0 to Integer.MAX_VALUE in seconds. The value 0 indicates that no failover is performed. If omitted, the default value used by this Factory is applied.
  containerCacheSize	The maximum number of ContainerInfos on the Container cache. A string representing of a number from 0 to Integer.MAX_VALUE. The Container cache is not used if the value is 0. To obtain a Container, its ContainerInfo might be obtained from the Container cache instead of request to GridDB. A default number is used if omitted.
  dataAffinityPattern	Specifies the arbitrary number of patterns as show below, using pairs of an affinity string for the function of data affinity and a container pattern. (ContainerNamePattern1)=(DataAffinityString1),(ContainerNamePattern2)=(DataAffinityString2),... When Container is added by ContainerInfo.setDataAffinity(String), the affinity string pairing with a container name pattern that matches the container name is applied. If there are multiple patterns that match the name, the first pattern in the specified order is selected. Each container name pattern follows the naming rules of container, except a wild card character '%' can also be specified in the pattern. The affinity string follows the rules of ContainerInfo.setDataAffinity(String). To specify special characters used in the patterns or as delimiters for the patterns in a container name, etc., they must be escaped by '\'. But the characters against the naming rules of container or affinity cannot be specified. Supported since the version 2.7.
  notificationMember	A list of address and port pairs in cluster. It is used to connect to cluster which is configured with FIXED_LIST mode, and specified as follows. (Address1):(Port1),(Address2):(Port2),... This property cannot be specified with neither notificationAddress nor notificationProvider properties at the same time. This property is supported on version 2.9 or later.
  notificationProvider	A URL of address provider. It is used to connect to cluster which is configured with PROVIDER mode. This property cannot be specified with neither notificationAddress nor notificationMember properties at the same time. This property is supported on version 2.9 or later.
  applicationName	Name of an application. It may be contained in various information for management on the connected cluster. However, the cluster shall not be involved with the identity of applications. If the property is omitted, it is regarded that the name is not specified. Empty string cannot be specified. This property is supported on version 4.2 or later.
  timeZone	Time zone information. It is used for TIMESTAMP value operations in TQL. Specifies an offset value in the "±hh:mm" or the "±hhmm" format (where ± is + or -, hh is hours, and mm is minutes), "Z" (equivalent to +00:00), or "auto" (automatically set according to the execution environment). "auto" can only be used for the time zone that does not observe the daylight saving time. This property is supported on version 4.3 or later.

  Cluster names, database names, user names and passwords are case-sensitive. See the GridDB Technical Reference for the details of the limitations, such as allowed characters and maximum length. When a name violating the limitations has been specified as a property value, the error detection may be delayed until the authentication processing. And there are the cases that the error is identified as an authentication error, etc., not a violation error for the limitations.

  A new GridStore instance is created by each call of this method. Operations on different GridStore instances and related objects are thread safe. That is, if some two objects are each created based on GridStore instances or they are just GridStore instances, and if they are related to different GridStore instances respectively, any method of one object can be called, no matter when a method of the other object may be called from any thread. However, since thread safety is not guaranteed for GridStore itself, it is not allowed to call a method of a single GridStore instance from two or more threads at an arbitrary time.

  Parameters:

  properties - Properties specifying the settings for the object to be obtained.

  Throws:

  GSException - if host name resolution fails.

  GSException - if any specified property does not match the format explained above. even if connection or authentication will not succeed with their values.

  GSException - if the connection is closed.

  java.lang.NullPointerException - null is specified as properties.
