# Class BeanContextEvent

java.lang.Object

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 `BeanContext`s. The `setPropagatedFrom()` and `getPropagatedFrom()` methods allow a `BeanContext` to identify itself as the source of a propagated event.
