java.beans.beancontext.BeanContextMembershipEvent
- All Implemented Interfaces:
- Serializable
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.- Since:
- 1.2
