Interface TransactionEntityMap.TxAssociation

Enclosing class:

TransactionEntityMap

public static interface TransactionEntityMap.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.

Methods

Modifier and Type	Method and Description
void	invokeEjbStore(Thread thread, CmpEntityBeanContext context) Invokes ejbStore if needed
void	scheduleSync(Transaction tx, CmpEntityBeanContext context) Schedules the instance for synchronization.
void	synchronize(Thread thread, Transaction tx, CmpEntityBeanContext context) Synchronizes the instance if it is needed.

Method Detail

scheduleSync

void scheduleSync(Transaction tx,
                CmpEntityBeanContext context)
                  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

context - the instance to be scheduled for synchronization

Throws:

SystemException

RollbackException

synchronize

void synchronize(Thread thread,
               Transaction tx,
               CmpEntityBeanContext context)
                 throws Exception

Synchronizes the instance if it is needed.

Parameters:

thread - current thread

tx - current transaction

context - the instance to be synchronized

Throws:

Exception - thrown if synchronization failed

invokeEjbStore

void invokeEjbStore(Thread thread,
                  CmpEntityBeanContext context)
                    throws Exception

Invokes ejbStore if needed

Parameters:

thread - current thread

context - the instance to be synchronized

Throws:

Exception - thrown if synchronization failed
