      • receive

        public void receive​(Message msg)
        Description copied from interface: Receiver
        Called when a message is received.
        Specified by:
        receive in interface Receiver
        Parameters:
        msg - The message

      • viewAccepted

        public void viewAccepted​(View new_view)
        Description copied from interface: Receiver
        Called when a change in membership has occurred. No long running actions, sending of messages or anything that could block 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 JChannel.connect(String) returns.
        Specified by:
        viewAccepted in interface Receiver

      • getState

        public void getState​(java.io.OutputStream out)
              throws java.lang.Exception
        Description copied from interface: Receiver
        Allows an application to write the state to an OutputStream. After the state has been written, the OutputStream doesn't need to be closed as stream closing is automatically done when a calling thread returns from this callback.
        Specified by:
        getState in interface Receiver
        Parameters:
        out - The OutputStream
        Throws:
        java.lang.Exception - If the streaming fails, any exceptions should be thrown so that the state requester can re-throw them and let the caller know what happened

      • setState

        public void setState​(java.io.InputStream input)
              throws java.lang.Exception
        Description copied from interface: Receiver
        Allows an application to read the state from an InputStream. After the state has been read, the InputStream doesn't need to be closed as stream closing is automatically done when a calling thread returns from this callback.
        Specified by:
        setState in interface Receiver
        Parameters:
        input - The InputStream
        Throws:
        java.lang.Exception - If the streaming fails, any exceptions should be thrown so that the state requester can catch them and thus know what happened
