org.jboss.resource.connectionmanager
Class TransactionSynchronizer

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

All Implemented Interfaces:: Synchronization (src)

public class TransactionSynchronizer
extends java.lang.Object
implements Synchronization (src)

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.

Field Summary
`protected Synchronization (src)`	`ccmSynch` The cached connection manager synchronization
`protected Transaction (src)`	`tx` The transaction
`protected java.util.ArrayList`	`txRemoverSynchs` TxRemover synchronizations
`protected static TransactionLocal (src)`	`txSynchs` The transaction synchronizations

Method Summary
`void`	`afterCompletion(int status)` This method is invoked after the transaction has committed or rolled back.
`void`	`beforeCompletion()` This method is invoked before the start of the commit process.
`static Synchronization (src)`	`getCCMSynchronization(Transaction (src) tx)` Check whether we have a CCM synchronization
`protected static TransactionSynchronizer (src)`	`getRegisteredSynchronizer(Transaction (src) tx)` Get a registered transaction synchronizer.
`protected void`	`invokeAfter(Synchronization (src) synch, int status)` Invoke an afterCompletion
`protected void`	`invokeBefore(Synchronization (src) synch)` Invoke a beforeCompletion
`static void`	`registerCCMSynchronization(Transaction (src) tx, Synchronization (src) synch)` Register a new CCM synchronization
`static void`	`registerTxRemoverSynchronization(Transaction (src) tx, Synchronization (src) synch)` Register a new TxRemover synchronization
`static void`	`setTransactionManager(TransactionManager (src) tm)` Initialization

Initialization

registerTxRemoverSynchronization

public static void registerTxRemoverSynchronization(Transaction (src)  tx,
                                                    Synchronization (src)  synch)
                                             throws RollbackException (src) ,
                                                    SystemException (src)

Parameters:: tx - the transaction; synch - the synchronization
Throws:: RolledbackException - if the transaction is already rolled back; SystemException (src) - for an error in the tranaction manager; RollbackException (src)

getCCMSynchronization

public static Synchronization (src)  getCCMSynchronization(Transaction (src)  tx)

Check whether we have a CCM synchronization

Parameters:: tx - the transaction

registerCCMSynchronization

public static void registerCCMSynchronization(Transaction (src)  tx,
                                              Synchronization (src)  synch)
                                       throws RollbackException (src) ,
                                              SystemException (src)

Parameters:: tx - the transaction; synch - the synchronization
Throws:: RolledbackException - if the transaction is already rolled back; SystemException (src) - for an error in the tranaction manager; RollbackException (src)

beforeCompletion

public void beforeCompletion()

Description copied from interface: Synchronization (src)

This method is invoked before the start of the commit process. The method invocation is done in the context of the transaction that is about to be committed.

Specified by:: beforeCompletion in interface Synchronization (src)

afterCompletion

public void afterCompletion(int status)

Description copied from interface: Synchronization (src)

This method is invoked after the transaction has committed or rolled back.

Specified by:: afterCompletion in interface Synchronization (src)

Parameters:: status - The status of the completed transaction.

invokeBefore

protected void invokeBefore(Synchronization (src)  synch)

Invoke a beforeCompletion

Parameters:: synch - the synchronization

invokeAfter

protected void invokeAfter(Synchronization (src)  synch,
                           int status)

Invoke an afterCompletion

Parameters:: synch - the synchronization; status - the status of the transaction

getRegisteredSynchronizer

protected static TransactionSynchronizer (src)  getRegisteredSynchronizer(Transaction (src)  tx)
                                                            throws RollbackException (src) ,
                                                                   SystemException (src)

Get a registered transaction synchronizer.

Parameters:: tx - the transaction
Returns:: the registered transaction synchronizer for this transaction
Throws:: RolledbackException - if the transaction is already rolled back; SystemException (src) - for an error in the tranaction manager; RollbackException (src)
