 * This class wraps an output stream, storing a reference to its originating
 * socket.  When the stream is closed, it will also close the socket
 * immediately afterward.  This class is useful for situations where you
 * are dealing with a stream originating from a socket, but do not have
 * a reference to the socket, and want to make sure it closes when the
 * stream closes.


* @author Daniel F. Savarese * @see SocketInputStream ***/ public class SocketOutputStream extends FilterOutputStream { private Socket __socket; /*** * Creates a SocketOutputStream instance wrapping an output stream and * storing a reference to a socket that should be closed on closing * the stream. *

* @param socket The socket to close on closing the stream. * @param stream The input stream to wrap. ***/ public SocketOutputStream(Socket socket, OutputStream stream) { super(stream); __socket = socket; } /*** * Writes a number of bytes from a byte array to the stream starting from * a given offset. This method bypasses the equivalent method in * FilterOutputStream because the FilterOutputStream implementation is * very inefficient. *

* @param buffer The byte array to write. * @param offset The offset into the array at which to start copying data. * @param length The number of bytes to write. * @exception IOException If an error occurs while writing to the underlying * stream. ***/ public void write(byte buffer[], int offset, int length) throws IOException { out.write(buffer, offset, length); } /*** * Closes the stream and immediately afterward closes the referenced * socket. *

* @exception IOException If there is an error in closing the stream * or socket. ***/ public void close() throws IOException { super.close(); __socket.close(); } }
