org.jboss.resource.connectionmanager
Class TransactionSynchronizer

java.lang.Object
  org.jboss.resource.connectionmanager.TransactionSynchronizer

All Implemented Interfaces:: Synchronization

public class TransactionSynchronizer
extends Object
implements Synchronization

Organizes transaction synchronization done by JCA.

This class exists to make sure all TxRemover synchronizations are invoked before the cached connection manager closes any closed connections.

Version:: $Revision: 1.1 $
Author:: Adrian Brock

Field Summary

protected Synchronization ccmSynch
          The cached connection manager synchronization

protected Transaction tx

protected ArrayList txRemoverSynchs
          TxRemover synchronizations

protected static org.jboss.tm.TransactionLocal txSynchs
          The transaction synchronizations

Method Summary

void afterCompletion(int status)


void beforeCompletion()


static Synchronization getCCMSynchronization(Transaction tx)
          Check whether we have a CCM synchronization

protected static TransactionSynchronizer getRegisteredSynchronizer(Transaction tx)
          Get a registered transaction synchronizer.

protected void invokeAfter(Synchronization synch, int status)
          Invoke an afterCompletion

protected void invokeBefore(Synchronization synch)
          Invoke a beforeCompletion

static void registerCCMSynchronization(Transaction tx, Synchronization synch)
          Register a new CCM synchronization

static void registerTxRemoverSynchronization(Transaction tx, Synchronization synch)
          Register a new TxRemover synchronization
