public class BeanContextMembershipEvent
extends BeanContextEvent
extends BeanContextEvent

A BeanContextMembershipEvent encapsulates the list of children added to, or removed from, the membership of a particular BeanContext. An instance of this event is fired whenever a successful add(), remove(), retainAll(), removeAll(), or clear() is 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 addBeanContextMembershipListener(BeanContextMembershipListener bcml) method.
