Class BeanContextEvent

java.lang.Object
 extended by java.util.EventObject
 extended by java.beans.beancontext.BeanContextEvent

All Implemented Interfaces:: Serializable

Direct Known Subclasses:: BeanContextMembershipEvent, BeanContextServiceAvailableEvent, BeanContextServiceRevokedEvent

public abstract class BeanContextEvent
extends EventObject
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
See Also:: BeanContext, Serialized Form

Field Summary
`protected BeanContext`	`propagatedFrom` The `BeanContext` from which this event was propagated

Fields inherited from class java.util.EventObject

Constructor Summary
`protected`	`BeanContextEvent(BeanContext bc)` Contruct a BeanContextEvent

Method Summary
`BeanContext`	`getBeanContext()` Gets the `BeanContext` associated with this event.
`BeanContext`	`getPropagatedFrom()` Gets the `BeanContext` from which this event was propagated.
`boolean`	`isPropagated()` Reports whether or not this event is propagated from some other `BeanContext`.
