Class ToEclipseQueue

  • All Implemented Interfaces:
    java.io.Closeable, java.io.Flushable, java.lang.AutoCloseable

    public class ToEclipseQueue
    extends java.io.OutputStream
    A queue for sending data from Java to ECLiPSe. This class performs no processing of the data and cannot for example, convert to EXDR format (see EXDROutputStream for a class which can do this).

    In addition to the standard methods inherited from its superclass, this class also provides the ability to attach a QueueListener object to the ToEclipseQueue, as a handler for data requests from ECLiPSe.

    There is no public constructor; to access an ToEclipseQueue use the createToEclipseQueue() of an object implementing the EclipseConnection interface or the getEclipseStdin() method of an object implementing the EclipseEngine interface.

                   throws java.io.IOException
        Specified by:
        write in class java.io.OutputStream
        Throws:
        java.io.IOException
      • write

        public void write​(byte[] b,
                          int off,
                          int len)
                   throws java.io.IOException
        Overrides:
        write in class java.io.OutputStream
        Throws:
        java.io.IOException
      • setListener

        public void setListener​(QueueListener l)
                         throws java.io.IOException
        Attach a QueueListener to this ToEclipseQueue for handling requests for data. When ECLiPSe tries to read from an empty queue with a QueueListener attached, the dataAvailable() method of the QueueListener is invoked.
        Throws:
        java.io.IOException
      • removeListener

        public void removeListener()
                            throws java.io.IOException
        Detach any QueueListener from this ToEclipseQueue.
        Throws:
        java.io.IOException
      • flush

        public void flush()
                   throws java.io.IOException
        Calls the superclass' flush method
