Class BeanContextEventjava.lang.Object | +--java.util.EventObject | +--java.beans.beancontext.BeanContextEvent
- All Implemented Interfaces:
- Serializable
- Direct Known Subclasses:
- BeanContextMembershipEvent, BeanContextServiceAvailableEvent, BeanContextServiceRevokedEvent
- public abstract class BeanContextEvent
- extends EventObject
BeanContextEvent is the abstract root event class for all events emitted from, and pertaining to the semantics of, a BeanContext. This class introduces a mechanism to allow the propagation of BeanContextEvent subclasses through a heirarchy of BeanContexts. The setPropagatedFrom() and getPropagatedFrom() methods allow a BeanContext to identify itself as the source of a propagated event.
