BeanContextEvent (Java 2 Platform SE 5.0) (original) (raw)

java.beans.beancontext

Class BeanContextEvent

java.lang.Object extended by 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 hierarchy of BeanContexts. The setPropagatedFrom() and getPropagatedFrom() methods allow a BeanContext to identify itself as the source of a propagated event.

Since:

1.2
