import java.util.Enumeration;

 * The CopyStreamAdapter will relay CopyStreamEvents to a list of listeners
 * when either of its bytesTransferred() methods are called.  Its purpose
 * is to facilitate the notification of the progress of a copy operation
 * performed by one of the static copyStream() methods in
 * to multiple listeners.  The static
 * copyStream() methods invoke the
 * bytesTransfered(long, int) of a CopyStreamListener for performance
 * reasons and also because multiple listeners cannot be registered given
 * that the methods are static.

public class CopyStreamAdapter implements CopyStreamListener
    private ListenerList internalListeners;

     * Creates a new copyStreamAdapter.
    public CopyStreamAdapter()
        internalListeners = new ListenerList();

     * This method is invoked by a CopyStreamEvent source after copying
     * a block of bytes from a stream.  The CopyStreamEvent will contain
     * the total number of bytes transferred so far and the number of bytes
     * transferred in the last write.  The CopyStreamAdapater will relay
     * the event to all of its registered listeners, listing itself as the
     * source of the event.
     * @param event The CopyStreamEvent fired by the copying of a block of
     *              bytes.
    public void bytesTransferred(CopyStreamEvent event)

     * This method is not part of the JavaBeans model and is used by the
     * static methods in the class for efficiency.
     * It is invoked after a block of bytes to inform the listener of the
     * transfer.  The CopyStreamAdapater will create a CopyStreamEvent
     * from the arguments and relay the event to all of its registered
     * listeners, listing itself as the source of the event.
     * @param totalBytesTransferred  The total number of bytes transferred
     *         so far by the copy operation.
     * @param bytesTransferred  The number of bytes copied by the most recent
     *          write.
     * @param streamSize The number of bytes in the stream being copied.
     *        This may be equal to CopyStreamEvent.UNKNOWN_STREAM_SIZE if
     *        the size is unknown.
    public void bytesTransferred(long totalBytesTransferred,
                                 int bytesTransferred, long streamSize)
        Enumeration listeners;
        CopyStreamEvent event;

        listeners = internalListeners.getListeners();

        event = new CopyStreamEvent(this,

        while (listeners.hasMoreElements())
            ((CopyStreamListener) (listeners.nextElement())).

     * Registers a CopyStreamListener to receive CopyStreamEvents.
     * Although this method is not declared to be synchronized, it is
     * implemented in a thread safe manner.
     * @param listener  The CopyStreamlistener to register.
    public void addCopyStreamListener(CopyStreamListener listener)

     * Unregisters a CopyStreamListener.  Although this method is not
     * synchronized, it is implemented in a thread safe manner.
     * @param listener  The CopyStreamlistener to unregister.
    public void removeCopyStreamListener(CopyStreamListener listener)
