org.jets3t.service.io.ProgressMonitoredInputStream
Input stream wrapper that tracks the number of bytes that have been read through the stream. When data is read through this stream the count of bytes is increased and the associated {@link BytesTransferredWatcher} object is notified of the count of bytes read. @author James Murty
