Interface ExternalTransactionController

All Known Implementing Classes:

AbstractTransactionController, JBossTransactionController, JTATransactionController, Oc4jTransactionController, SunAS9TransactionController, WebLogicTransactionController, WebSphereTransactionController

public interface ExternalTransactionController

Purpose: Interface for external transaction management.

Description: This interface represents a delegate to be used for external transaction management. The implementing class may interface to an OMG OTS service, a Java JTA service or a manufacturer's specific implementation of these services.

Responsibilities:

• Define the API for UnitOfWork to add a listener to the externally controlled transaction.

org.eclipse.persistence.internal.sequencing.SequencingCallback	getActiveSequencingCallback(DatabaseSession dbSession, org.eclipse.persistence.internal.sequencing.SequencingCallbackFactory sequencingCallbackFactory) INTERNAL: Returns sequencingCallback for the current active external transaction.
org.eclipse.persistence.internal.sessions.UnitOfWorkImpl	getActiveUnitOfWork() INTERNAL: Return the active unit of work for the current active external transaction.
org.eclipse.persistence.internal.sessions.AbstractSession	getSession() INTERNAL: Return the manager's session.
void	initializeSequencingListeners() INTERNAL: Initializes sequencing listeners.
void	markTransactionForRollback() INTERNAL: Marks the external transaction for rollback only.
void	registerSynchronizationListener(org.eclipse.persistence.internal.sessions.UnitOfWorkImpl uow, org.eclipse.persistence.internal.sessions.AbstractSession session) INTERNAL: Register a listener on the unit of work.

void	setSession(org.eclipse.persistence.internal.sessions.AbstractSession session) INTERNAL: Set the manager's session.

Method Detail

beginTransaction

void beginTransaction(org.eclipse.persistence.internal.sessions.AbstractSession session)

INTERNAL: Begin a transaction externally. This allows for EclipseLink to force a JTS transaction.

commitTransaction

void commitTransaction(org.eclipse.persistence.internal.sessions.AbstractSession session)

INTERNAL: Commit a transaction externally. This allows for EclipseLink to force a JTS transaction.

getActiveUnitOfWork

org.eclipse.persistence.internal.sessions.UnitOfWorkImpl getActiveUnitOfWork()

INTERNAL: Return the active unit of work for the current active external transaction.

getSession

org.eclipse.persistence.internal.sessions.AbstractSession getSession()

INTERNAL: Return the manager's session.

registerSynchronizationListener

void registerSynchronizationListener(org.eclipse.persistence.internal.sessions.UnitOfWorkImpl uow,
                                     org.eclipse.persistence.internal.sessions.AbstractSession session)
                                     throws DatabaseException

INTERNAL: Register a listener on the unit of work. The listener will callback to the unit of work to tell it to commit and merge.

Throws:

DatabaseException

rollbackTransaction

void rollbackTransaction(org.eclipse.persistence.internal.sessions.AbstractSession session)

INTERNAL: Rollback a transaction externally. This allows for EclipseLink to force a JTS transaction.

markTransactionForRollback

void markTransactionForRollback()

INTERNAL: Marks the external transaction for rollback only.

setSession

void setSession(org.eclipse.persistence.internal.sessions.AbstractSession session)

INTERNAL: Set the manager's session.

initializeSequencingListeners

void initializeSequencingListeners()

INTERNAL: Initializes sequencing listeners. Always clears sequencing listeners first. There are two methods calling this method: 1. setSession method - this could lead to initialization of sequencing listeners only if sequencing already connected (that would happen if setSession is called after session.login, which is normally not the case). 2. in the very end of connecting sequencing, after it's determined whether sequencing callbacks (and therefore listeners) will be required.

getActiveSequencingCallback

org.eclipse.persistence.internal.sequencing.SequencingCallback getActiveSequencingCallback(DatabaseSession dbSession,
                                                                                           org.eclipse.persistence.internal.sequencing.SequencingCallbackFactory sequencingCallbackFactory)

INTERNAL: Returns sequencingCallback for the current active external transaction. DatabaseSession is passed for the sake of SessionBroker case. This method requires active external transaction.

clearSequencingListeners

void clearSequencingListeners()

INTERNAL: Clears sequencing listeners. Called by initializeSequencingListeners and by sequencing on disconnect.
