Interface GlobalTxEntityMap.TxAssociation

Enclosing interface:

GlobalTxEntityMap

public static interface GlobalTxEntityMap.TxAssociation

An instance can be in one of the three states:

• not associated with the tx and, hence, does not need to be synchronized
• associated with the tx and needs to be synchronized
• associated with the tx but does not need to be synchronized

Implementations of TxAssociation implement these states.

Method Summary

void	invokeEjbStore(Thread thread, EntityEnterpriseContext instance) Invokes ejbStore if needed
void	scheduleSync(Transaction tx, EntityEnterpriseContext instance) Schedules the instance for synchronization.
void	synchronize(Thread thread, Transaction tx, EntityEnterpriseContext instance) Synchronizes the instance if it is needed.

Method Detail

scheduleSync

public void scheduleSync(Transaction tx,
                         EntityEnterpriseContext instance)
                  throws SystemException,
                         RollbackException

Schedules the instance for synchronization. The instance might or might not be associated with the tx.

Parameters:

tx - the transaction the instance should be associated with if not yet associated

instance - the instance to be scheduled for synchronization

Throws:

SystemException

RollbackException

synchronize

public void synchronize(Thread thread,
                        Transaction tx,
                        EntityEnterpriseContext instance)
                 throws Exception

Synchronizes the instance if it is needed.

Parameters:

thread - current thread

tx - current transaction

instance - the instance to be synchronized

Throws:

Exception - thrown if synchronization failed

invokeEjbStore

public void invokeEjbStore(Thread thread,
                           EntityEnterpriseContext instance)
                    throws Exception

Invokes ejbStore if needed

Parameters:

thread - current thread

instance - the instance to be synchronized

Throws:

Exception - thrown if synchronization failed
