Method Detail

basicBeginTransaction

protected void basicBeginTransaction(org.eclipse.persistence.internal.sessions.AbstractSession session)
                              throws EISException

Begin a local transaction.

Specified by:

basicBeginTransaction in class org.eclipse.persistence.internal.databaseaccess.DatasourceAccessor

Throws:

EISException

closeDatasourceConnection

protected void closeDatasourceConnection()

Close the connection.

Specified by:

closeDatasourceConnection in class org.eclipse.persistence.internal.databaseaccess.DatasourceAccessor

basicCommitTransaction

protected void basicCommitTransaction(org.eclipse.persistence.internal.sessions.AbstractSession session)
                               throws EISException

Commit the local transaction.

Specified by:

basicCommitTransaction in class org.eclipse.persistence.internal.databaseaccess.DatasourceAccessor

Throws:

EISException

buildConnectLog

protected void buildConnectLog(org.eclipse.persistence.internal.sessions.AbstractSession session)

If logging is turned on and the CCI implementation supports meta data then display connection info.

Specified by:

buildConnectLog in class org.eclipse.persistence.internal.databaseaccess.DatasourceAccessor

executeCall

public java.lang.Object executeCall(Call call,
                                    org.eclipse.persistence.internal.sessions.AbstractRecord translationRow,
                                    org.eclipse.persistence.internal.sessions.AbstractSession session)
                             throws DatabaseException

Avoid super to have logging occur after possible manual auto-commit.

Specified by:

executeCall in interface org.eclipse.persistence.internal.databaseaccess.Accessor

Overrides:

executeCall in class org.eclipse.persistence.internal.databaseaccess.DatasourceAccessor

Throws:

DatabaseException

basicExecuteCall

public java.lang.Object basicExecuteCall(Call call,
                                         org.eclipse.persistence.internal.sessions.AbstractRecord translationRow,
                                         org.eclipse.persistence.internal.sessions.AbstractSession session)
                                  throws DatabaseException

Execute the interaction. The execution can differ slightly depending on the type of interaction. The call may be parameterized where the arguments are in the translation row. The row will be empty if there are no parameters.

Specified by:

basicExecuteCall in class org.eclipse.persistence.internal.databaseaccess.DatasourceAccessor

Returns:

depending of the type either the row count, row or vector of rows.

Throws:

DatabaseException

getCCIConnection

public javax.resource.cci.Connection getCCIConnection()

Return the CCI connection to the EIS resource adapter.

getEISPlatform

public EISPlatform getEISPlatform()

Return and cast the platform.

getRecordFactory

public javax.resource.cci.RecordFactory getRecordFactory()

Return the RecordFactory. The record factory is acquired from the ConnectionManager, and used to create record to pass to interactions.

setRecordFactory

basicRollbackTransaction in class org.eclipse.persistence.internal.databaseaccess.DatasourceAccessor

Throws:

DatabaseException

isDatasourceConnected

protected boolean isDatasourceConnected()

Return if the connection to the "data source" is connected.

Specified by:

isDatasourceConnected in class org.eclipse.persistence.internal.databaseaccess.DatasourceAccessor
