Enum Class TransactionPhase
- All Implemented Interfaces:
Serializable
,Comparable<TransactionPhase>
,Constable
Distinguishes the various kinds of transactional observer methods from regular observer methods which are notified immediately.
Transactional observer methods are observer methods which receive event notifications during the before or after completion phase of the transaction in which the event was fired. If no transaction is in progress when the event is fired, they are notified at the same time as other observers.
