Class MembershipListenerAdapter

  • All Implemented Interfaces:
    MembershipListener
    public class MembershipListenerAdapter
extends java.lang.Object
implements MembershipListener
    This class provides multiplexing possibilities for MembershipListener instances. Usually, we have more than one instance willing to listen to membership messages. PullPushAdapter allows only one instance of MembershipListener to be registered for message notification. With help of this class you can overcome this limitation.
