      • getLocalChannel

        public int getLocalChannel()
        Returns:
        the local channel onto which this Session is bound.
      • getRemoteChannel

        public int getRemoteChannel()

      • open

        public ProtonSession open()
                           throws IllegalStateException,
                                  EngineStateException
        Description copied from interface: Endpoint
        Open the end point locally, sending the Open performative immediately if possible or holding it until SASL negotiations or the AMQP header exchange and other required performative exchanges has completed. The end point will signal any registered handler of the remote opening the Connection once the remote performative that signals open completion arrives.
        Specified by:
        open in interface Endpoint<Session>
        Returns:
        this Endpoint instance.
        Throws:
        EngineStateException - if an error occurs opening the Connection or the Engine is shutdown.
        IllegalStateException
      • close

        public ProtonSession close()
                            throws EngineFailedException
        Description copied from interface: Endpoint
        Close the end point locally and send the closing performative immediately if possible or holds it until the Connection / Engine state allows it. If the engine encounters an error writing the performative or the engine is in a failed state from a previous error then this method will throw an exception. If the engine has been shutdown then this method will close out the local end of the Endpoint and clean up any local resources before returning normally.
        Specified by:
        close in interface Endpoint<Session>
        Returns:
        this Endpoint instance.
        Throws:
        EngineFailedException - if an error occurs closing the end point or the Engine is in a failed state.
