flush

public void flush()

Description copied from interface: SmartTransactionObject

Flush the underlying sessions to the datastore, if applicable: for example, all affected Hibernate/JPA sessions.

Specified by:

flush in interface java.io.Flushable

Specified by:

flush in interface SmartTransactionObject

Overrides:

flush in class JdbcTransactionObjectSupport

createSavepoint

public java.lang.Object createSavepoint()
                                 throws TransactionException

Description copied from class: JdbcTransactionObjectSupport

This implementation creates a JDBC 3.0 Savepoint and returns it.

Specified by:

createSavepoint in interface SavepointManager

Overrides:

createSavepoint in class JdbcTransactionObjectSupport

Returns:

a savepoint object, to be passed into SavepointManager.rollbackToSavepoint(java.lang.Object) or SavepointManager.releaseSavepoint(java.lang.Object)

Throws:

NestedTransactionNotSupportedException - if the underlying transaction does not support savepoints

TransactionException - if the savepoint could not be created, for example because the transaction is not in an appropriate state

See Also:

Connection.setSavepoint()

rollbackToSavepoint

                         throws TransactionException

Description copied from class: JdbcTransactionObjectSupport

This implementation rolls back to the given JDBC 3.0 Savepoint.

Specified by:

rollbackToSavepoint in interface SavepointManager

Overrides:

rollbackToSavepoint in class JdbcTransactionObjectSupport

Parameters:

savepoint - the savepoint to roll back to

Throws:

NestedTransactionNotSupportedException - if the underlying transaction does not support savepoints

TransactionException - if the rollback failed

See Also:

Connection.rollback(java.sql.Savepoint)

releaseSavepoint

public void releaseSavepoint(java.lang.Object savepoint)
                      throws TransactionException

Description copied from class: JdbcTransactionObjectSupport

This implementation releases the given JDBC 3.0 Savepoint.

Specified by:

releaseSavepoint in interface SavepointManager

Overrides:

releaseSavepoint in class JdbcTransactionObjectSupport

Parameters:

savepoint - the savepoint to release

Throws:

NestedTransactionNotSupportedException - if the underlying transaction does not support savepoints

TransactionException - if the release failed
