java.lang.Object

org.clapper.util.io.NotFilenameFilter

All Implemented Interfaces:

java.io.FilenameFilter

public class NotFilenameFilter
extends java.lang.Object
implements java.io.FilenameFilter

NotFilenameFilter is a FilenameFilter that wraps another FilenameFilter 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 do not start with the letter "A".

 NotFilenameFilter filter = new NotFilenameFilter (new RegexFilenameFilter ("^[Aa]", FileFilterMatchType.NAME));
