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.
