    • setUdpBinding

      public void setUdpBinding(UdpBindingService udpBinding)
      Description copied from interface: UdpMessageQueueService
      Injects the UDP binding service.

      Without a UDP binding service the message queue cannot send and receive messages. Make sure the UDP binding is injected before the service is started.

      Specified by:
      setUdpBinding in interface UdpMessageQueueService
      Parameters:
      udpBinding - the UDP binding service to inject.

    • sendMessage

      public boolean sendMessage(UdpMessage message)
      Description copied from interface: UdpMessageQueueService
      Queues an outgoing UDP message.
      Specified by:
      sendMessage in interface UdpMessageQueueService
      Parameters:
      message - the message to be send.
      Returns:
      true if the message could be queued, otherwise false (queue overflow).

    • registerUdpMessageQueueObserver

      public void registerUdpMessageQueueObserver(UdpMessageQueueObserver observer)
      Description copied from interface: UdpMessageQueueService
      Registers an observer to receive incoming UDP messages.
      Specified by:
      registerUdpMessageQueueObserver in interface UdpMessageQueueService
      Parameters:

      Specified by:
      unregisterUdpMessageQueueObserver in interface UdpMessageQueueService
      Parameters:
      observer - the observer to unregister.

    • startUp
