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

Overrides:

write in class java.io.OutputStream

write

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

Overrides:

write in class java.io.OutputStream

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.

removeListener

public void removeListener()
                    throws java.io.IOException

Detach any QueueListener from this ToEclipseQueue.

flush

public void flush()
           throws java.io.IOException

Calls the superclass' flush method

Overrides:

flush in class java.io.OutputStream

close

public void close()
           throws java.io.IOException

Closes the queue (both eclipse and Java sides), removing any listener.

Overrides:

close in class java.io.OutputStream
