java.lang.Objectorg.apache.openjpa.event.LifecycleEventManager
public class LifecycleEventManager
Manager that can be used to track and notify listeners on lifecycle events. This class is optimized for event firing rather than for adding and removing listeners, which are O(n) operations. This class also does not maintain perfect set semantics for listeners; it is possible to wind up having the same listener invoked multiple times for a single event if it is added to this manager multiple times with different classes, or with a base class and its subclass.
