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
