111<P>
112A <code>FilterFileSystem</code> contains
113 some other file system, which it uses as
114 its  basic file system, possibly transforming
115 the data along the way or providing  additional
116 functionality. The class <code>FilterFileSystem</code>
117 itself simply overrides all  methods of
118 <code>FileSystem</code> with versions that
119 pass all requests to the contained  file
120 system. Subclasses of <code>FilterFileSystem</code>
121 may further override some of  these methods
122 and may also provide additional methods
123 and fields.
