Class BeanContextEvent

Implemented Interfaces:
Serializable
Known Direct 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 hierarchy of BeanContexts. The setPropagatedFrom() and getPropagatedFrom() methods allow a BeanContext to identify itself as the source of a propagated event.
