      • close

        public void close()
        Description copied from interface: PortAutoCloseable
        Closes the channel so that no more messages could be sent to it. Messages already sent to the channel will still be received.

        public boolean isClosed()
        Description copied from interface: PortAutoCloseable
        Tests whether the channel has been closed and no more messages await in the channel. If this method returns true all future calls to receive are guaranteed to return null, and calls to receive on a primitive channel will throw a EOFException.
        Specified by:
        isClosed in interface PortAutoCloseable
        Returns:
        true if the channels has been closed and no more messages will be received; false otherwise.
