Interface TransactionStore.RollbackListener

All Known Implementing Classes:
SessionLocal
Enclosing class:
TransactionStore

public static interface TransactionStore.RollbackListener
This listener can be registered with the transaction to be notified of every compensating change during transaction rollback. Normally this is not required, if no external resources were modified, because state of all transactional maps will be restored automatically. Only state of external resources, possibly modified by triggers need to be restored.
