Class FilterPath

java.lang.Object

org.apache.lucene.mockfile.FilterPath

All Implemented Interfaces:

Comparable<Path>, Iterable<Path>, Path, Watchable

public class FilterPath
extends Object
implements Path

A FilterPath contains another Path, which it uses as its basic source of data, possibly transforming the data along the way or providing additional functionality.
