Interface QueueListener

public interface QueueListener
Interface for handlers of incoming data or data requests on queues. Any object which implements QueueListener can be attached to a FromEclipseQueue or a ToEclipseQueue using the setListener() methods of those classes.

If attached to a FromEclipseQueue, when ECLiPSe flushes the queue, the dataAvailable() method is called with the flushed FromEclipseQueue as the source parameter.

If attached to a ToEclipseQueue, when ECLiPSe tries to read data from that queue and it is empty, the dataRequest() method is called with the ToEclipseQueue as the source parameter.

  • Method Details

    • dataAvailable

      void dataAvailable(Object source)
      Called with FromEclipseQueue as source when the QueueListener is attached and ECLiPSe flushes the queue. If used with an instance of RemoteEclipse, the resume() method should not be invoked during dataAvailable().

    • dataRequest

      void dataRequest(Object source)
      Called with ToEclipseQueue as source when the QueueListener is attached and ECLiPSe tries to read data from the queue when it is empty. If used with an instance of RemoteEclipse, the resume() method should not be invoked during dataRequest().
