MembershipListener

The MembershipListener interface (JavaGroups.MembershipListener) is similar to the MessageListener interface above: every time a new view, a suspicion message, or a block event is received, the corresponding method of the class implementing MembershipListener will be called.

        public interface MembershipListener {    
            public void ViewAccepted(View new_view);
            public void Suspect(Object suspected_mbr);
            public void Block();
        }
