Class ToEclipseQueue

java.lang.Object
  extended byjava.io.OutputStream
      extended bycom.parctechnologies.eclipse.ToEclipseQueue

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.


Method Summary
 void close()
          Closes the queue (both eclipse and Java sides), removing any listener.
 void flush()
          Calls the superclass' flush method
 void removeListener()
          Detach any QueueListener from this ToEclipseQueue.
 void setListener(QueueListener l)
          Attach a QueueListener to this ToEclipseQueue for handling requests for data.
 void write(byte[] b, int off, int len)
           
 void write(int b)

Method Detail

write

public void write(int b)
           throws java.io.IOException
Throws:
java.io.IOException

write

public void write(byte[] b,
                  int off,
                  int len)
           throws java.io.IOException
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

Throws:
java.io.IOException

close

public void close()
           throws java.io.IOException
Closes the queue (both eclipse and Java sides), removing any listener.

Throws:
java.io.IOException
