      • getNumMessages

        public long getNumMessages()

      • getTotalTime

        public long getTotalTime()
      • getName

        public java.lang.String getName()
        Specified by:
        getName in class Protocol
      • init

        public void init()
                  throws java.lang.Exception
        Description copied from class: Protocol
        Called after instance has been created (null constructor) and before protocol is started. Properties are already set. Other protocols are not yet connected and events cannot yet be sent.
        Overrides:
        init in class Protocol
        Throws:
        java.lang.Exception - Thrown if protocol cannot be initialized successfully. This will cause the ProtocolStack to fail, so the channel constructor will throw an exception
      • start

        public void start()
                   throws java.lang.Exception
        Description copied from class: Protocol
        This method is called on a Channel.connect(String). Starts work. Protocols are connected and queues are ready to receive events. Will be called from bottom to top. This call will replace the START and START_OK events.
        Overrides:
        start in class Protocol
        Throws:
        java.lang.Exception - Thrown if protocol cannot be started successfully. This will cause the ProtocolStack to fail, so Channel.connect(String) will throw an exception
      • down

        public java.lang.Object down​(Event evt)
        Caller by the layer above this layer. Usually we just put this Message into the send queue and let one or more worker threads handle it. A worker thread then removes the Message from the send queue, performs a conversion and adds the modified Message to the send queue of the layer below it, by calling Down).
        Overrides:
        down in class Protocol
      • up

        public java.lang.Object up​(Event evt)
        Description copied from class: Protocol
        An event was received from the layer below. Usually the current layer will want to examine the event type and - depending on its type - perform some computation (e.g. removing headers from a MSG event type, or updating the internal membership list when receiving a VIEW_CHANGE event). Finally the event is either a) discarded, or b) an event is sent down the stack using down_prot.down() or c) the event (or another event) is sent up the stack using up_prot.up().
        Overrides:
        up in class Protocol
