1.33 - * streams. These streams sit on top of an already existing output
1.34 - * stream (the <i>underlying</i> output stream) which it uses as its
1.35 - * basic sink of data, but possibly transforming the data along the
1.36 - * way or providing additional functionality.

1.38 - * The class <code>FilterOutputStream</code> itself simply overrides
1.39 - * all methods of <code>OutputStream</code> with versions that pass
1.40 - * all requests to the underlying output stream. Subclasses of
1.41 - * <code>FilterOutputStream</code> may further override some of these
1.42 - * methods as well as provide additional methods and fields.
