BeanContextMembershipEventpublic class BeanContextMembershipEvent 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. |
