Method Details

release

public void release()

Release this connection. Releasing this connection will allow this managed connection to be used one or more times inside the same transaction. If this managed connection is managed by a transaction manager, release is a no-op, otherwise the physical connection is closed

Specified by:

release in interface org.datanucleus.store.connection.ManagedConnection

Overrides:

release in class org.datanucleus.store.connection.AbstractManagedConnection

getXAResource

public XAResource getXAResource()

Obtain an XAResource which can be enlisted in a transaction

Specified by:

getXAResource in interface org.datanucleus.store.connection.ManagedConnection

Overrides:

getXAResource in class org.datanucleus.store.connection.AbstractManagedConnection

getConnection

public Object getConnection()

Create a connection to the resource

close

public void close()

Close the connection

Specified by:

close in interface org.datanucleus.store.connection.ManagedConnection

Overrides:

close in class org.datanucleus.store.connection.AbstractManagedConnection

getSqlConnection

private Connection getSqlConnection()

Convenience accessor for the java.sql.Connection in use (if any).

Returns:

SQL Connection

setSavepoint

public void setSavepoint(String name)

Specified by:

setSavepoint in interface org.datanucleus.store.connection.ManagedConnection

Overrides:

setSavepoint in class org.datanucleus.store.connection.AbstractManagedConnection

releaseSavepoint

public void releaseSavepoint(String name)

Specified by:

releaseSavepoint in interface org.datanucleus.store.connection.ManagedConnection

Overrides:

releaseSavepoint in class org.datanucleus.store.connection.AbstractManagedConnection

rollbackToSavepoint

public void rollbackToSavepoint(String name)

Specified by:

rollbackToSavepoint in interface org.datanucleus.store.connection.ManagedConnection

Overrides:

rollbackToSavepoint in class org.datanucleus.store.connection.AbstractManagedConnection

closeAfterTransactionEnd

public boolean closeAfterTransactionEnd()

Specified by:

closeAfterTransactionEnd in interface org.datanucleus.store.connection.ManagedConnection

Overrides:

closeAfterTransactionEnd in class org.datanucleus.store.connection.AbstractManagedConnection
