public abstract class BeanContextEvent extends EventObject
BeanContextEventis the abstract root event class for all events emitted from, and pertaining to the semantics of, aBeanContext. This class introduces a mechanism to allow the propagation ofBeanContextEventsubclasses through a hierarchy ofBeanContexts. ThesetPropagatedFrom()andgetPropagatedFrom()methods allow aBeanContextto identify itself as the source of a propagated event.- Since:
