      • getState

        public byte[] getState()
        Description copied from interface: MessageListener
        Answers the group state; e.g., when joining.
        Specified by:
        getState in interface MessageListener
        Returns:
        byte[]
      • setState

        public void setState​(byte[] state)
        Description copied from interface: MessageListener
        Sets the group state; e.g., when joining.
        Specified by:
        setState in interface MessageListener
      • viewAccepted

        public void viewAccepted​(View new_view)
        Description copied from interface: MembershipListener
        Called when a change in membership has occurred. No long running actions or sending of messages should be done in this callback. If some long running action needs to be performed, it should be done in a separate thread.

        Note that on reception of the first view (a new member just joined), the channel will not yet be in the connected state. This only happens when Channel.connect(String) returns.

        viewAccepted in interface MembershipListener
      • suspect

        public void suspect​(Address suspected_mbr)
        Description copied from interface: MembershipListener
        Called whenever a member is suspected of having crashed, but has not yet been excluded.
        Specified by:
        suspect in interface MembershipListener
      • block

        public void block()
        Description copied from interface: MembershipListener
        Called (usually by the FLUSH protocol), as an indication that the member should stop sending messages. Any messages sent after returning from this callback might get blocked by the FLUSH protocol. When the FLUSH protocol is done, and messages can be sent again, the FLUSH protocol will simply unblock all pending messages. If a callback for unblocking is desired, implement ExtendedMembershipListener.unblock(). Note that block() is the equivalent of reception of a BlockEvent in the pull mode.

        block in interface MembershipListener
