Examples of javax.jdo.listener.InstanceLifecycleEvent

javax.jdo.listener.InstanceLifecycleEvent
This is the event class used in life cycle event notifications.
Note that although InstanceLifecycleEvent inherits Serializable interface from EventObject, it is not intended to be Serializable. Appropriate serialization methods are implemented to throw NotSerializableException. @version 2.0 @since 2.0
