112 | A <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. |
