• java.lang.Object
  • SynchronizationPOA

Fields Summary
private static POA	poa
private Synchronization	thisRef
private Long	localTID
private TopCoordinator	coordinator
static Logger	_logger

Constructors Summary
CoordinatorSynchronizationImpl() Default CoordinatorSynchronizationImpl constructor. param return see
CoordinatorSynchronizationImpl(TopCoordinator coord) Sets up a new CoordinatorSynchronizationImpl object with the Coordinator reference so that it can pass on synchronization requests. param coord The Coordinator for the transaction. return see // Set the instance variables to the values passed in. coordinator = coord; try { localTID = new Long(coord.getLocalTID()); } catch( SystemException exc ) {}

Methods Summary
public void	after_completion(Status status) Passes on the after completion operation to the Coordinator. param status The state of the transaction. return exception SystemException The operation failed. The minor code provides a reason for the failure. see // If there is no Coordinator reference, raise an exception. if( coordinator == null ) { INTERNAL exc = new INTERNAL(MinorCode.NoCoordinator, CompletionStatus.COMPLETED_NO); throw exc; } // Pass the after completion operation on to the coordinator. // Destroy myself. coordinator.afterCompletion(status); destroy();
public void	before_completion() Passes on the before completion operation to the Coordinator. param return exception SystemException The operation failed. The minor code provides a reason for the failure. see // If there is no Coordinator reference, raise an exception. if( coordinator == null ) { INTERNAL exc = new INTERNAL(MinorCode.NoCoordinator, CompletionStatus.COMPLETED_NO); throw exc; } // Pass the before completion operation on to the coordinator. coordinator.beforeCompletion();
void	destroy() Destroys the CoordinatorSynchronizationImpl object. param return see if( poa != null && thisRef != null ) try { poa.deactivate_object(poa.reference_to_id(thisRef)); thisRef = null; } catch( Exception exc ) { _logger.log(Level.WARNING,"jts.object_destroy_error", "CoordinatorResource"); } //finalize(); coordinator = null;
Synchronization	object() Returns the CORBA Object which represents this object. param return The CORBA object. see if( poa == null ) poa = Configuration.getPOA("transient"/*#Frozen*/); if( thisRef == null ) { if( poa == null ) poa = Configuration.getPOA("transient"/*#Frozen*/); try { poa.activate_object(this); thisRef = SynchronizationHelper. narrow(poa.servant_to_reference(this)); //thisRef = (Synchronization)this; } catch( ServantAlreadyActive saexc ) { _logger.log(Level.SEVERE, "jts.create_CoordinatorSynchronization_object_error"); String msg = LogFormatter.getLocalizedMessage(_logger, "jts.create_CoordinatorSynchronization_object_error"); throw new org.omg.CORBA.INTERNAL(msg); } catch( ServantNotActive snexc ) { _logger.log(Level.SEVERE, "jts.create_CoordinatorSynchronization_object_error"); String msg = LogFormatter.getLocalizedMessage(_logger, "jts.create_CoordinatorSynchronization_object_error"); throw new org.omg.CORBA.INTERNAL(msg); } catch( Exception exc ) { _logger.log(Level.SEVERE, "jts.create_CoordinatorSynchronization_object_error"); String msg = LogFormatter.getLocalizedMessage(_logger, "jts.create_CoordinatorSynchronization_object_error"); throw new org.omg.CORBA.INTERNAL(msg); } } return thisRef;
static final synchronized com.sun.jts.CosTransactions.CoordinatorSynchronizationImpl	servant(Synchronization sync) Returns the CoordinatorSynchronizationImpl which serves the given object. param The CORBA Object. return The CoordinatorSynchronizationImpl object which serves it. see CoordinatorSynchronizationImpl result = null; // we will not be able to obtain the // servant from our local POA for a proxy sync object. // so return null if (sync != null && Configuration.getProxyChecker().isProxy(sync)) { return result; } if (sync instanceof CoordinatorSynchronizationImpl ) { result = (CoordinatorSynchronizationImpl) sync; } else if (poa != null) { try { result = (CoordinatorSynchronizationImpl) poa.reference_to_servant(sync); if( result.thisRef == null ) result.thisRef = sync; } catch( Exception exc ) { _logger.log(Level.WARNING,"jts.cannot_locate_servant", "CoordinatorSynchronization"); } } return result;
