Class JTASynchronizationListener

java.lang.Object

org.eclipse.persistence.transaction.AbstractSynchronizationListener

org.eclipse.persistence.transaction.JTASynchronizationListener

All Implemented Interfaces:

Synchronization, SynchronizationListenerFactory

public class JTASynchronizationListener
extends AbstractSynchronizationListener
implements SynchronizationListenerFactory

Purpose: Synchronization object implementation for JTA 1.0

Description: Instances of this class are registered against JTA 1.0 transactions. This class may be subclassed to provide specialized behavior for specific transaction implementations. Subclasses must implement the newListener() method to return an instances of the listener subclass.

Constructor Details

JTASynchronizationListener

public JTASynchronizationListener()

PUBLIC: Used to create factory instances only. Use the "full-bodied" constructor for creating proper listener instances.

JTASynchronizationListener

public JTASynchronizationListener(UnitOfWorkImpl unitOfWork,
 AbstractSession session,
 Object transaction,
 AbstractTransactionController controller)

INTERNAL: Constructor for creating listener instances (expects all required state info)

Method Details

newSynchronizationListener

public AbstractSynchronizationListener newSynchronizationListener(UnitOfWorkImpl unitOfWork,
 AbstractSession session,
 Object transaction,
 AbstractTransactionController controller)

INTERNAL: Create and return the Synchronization listener object that can be registered to receive JTA transaction notification callbacks.

Specified by:

newSynchronizationListener in interface SynchronizationListenerFactory

beforeCompletion

public void beforeCompletion()

INTERNAL: Called by the JTA transaction manager prior to the start of the transaction completion process. This call is executed in the same transaction context of the caller who initiates the TransactionManager.commit, or the call is executed with no transaction context if Transaction.commit is used.

Specified by:

beforeCompletion in interface Synchronization

Overrides:

beforeCompletion in class AbstractSynchronizationListener

afterCompletion

public void afterCompletion(int stat)

INTERNAL: Called by the JTA transaction manager after the transaction is committed or rolled back. This method executes without a transaction context.

Specified by:

afterCompletion in interface Synchronization

Parameters:

stat - The status of the transaction completion.
