public class BeanContextMembershipEvent extends BeanContextEvent

An instance of this event is fired whenever a successful

invoked on a given BeanContext instance.
Objects interested in receiving events of this type must
implement the BeanContextMembershipListener
interface, and must register their intent via the
BeanContext's
