java.lang.Object
  org.clapper.util.io.NotFileFilter

All Implemented Interfaces:

java.io.FileFilter

public class NotFileFilter
extends java.lang.Object
implements java.io.FileFilter

NotFileFilter is a FileFilter that wraps another FileFilter and negates the sense of the wrapped filter's accept() method. This class conceptually provides a logical "NOT" operator for file filters. For example, the following code fragment will create a filter that finds all files that are not directories.

 NotFileFilter filter = new NotFileFilter (new DirectoryFilter());
