| 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. |
