      • close

        public void close​(java.lang.Throwable t)
        Description copied from interface: SendPort
        Closes the channel so that no more messages could be sent to it, and signifies an exception occurred in the producer. The exception will be thrown when the consumer calls ReceivePort's receive or tryReceive, wrapped by a ProducerException. Messages already sent to the channel prior to calling this method will still be received.
        Specified by:
        close in interface SendPort<Message>
        Parameters:
        t - the exception causing the close

      • 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.
        Specified by:
        close in interface java.lang.AutoCloseable
        Specified by:
        close in interface PortAutoCloseable

      • trySend

        public boolean trySend​(Message message)
        Description copied from interface: SendPort
        Sends a message to the channel if the channel has room available. This method never blocks.
        Specified by:
        trySend in interface SendPort<Message>
        Parameters:
        message - the message
        Returns:

          throws SuspendExecution,
                 java.lang.InterruptedException
        Description copied from interface: SendPort
        Sends a message to the channel, possibly blocking until there's room available in the channel. If the channel is full, this method may block, throw an exception, silently drop the message, or displace an old message from the channel. The behavior is determined by the channel's OverflowPolicy, set at construction time.
        Specified by:
        send in interface SendPort<Message>
        Parameters:
        message - the message
        Throws:
