All Implemented Interfaces:

java.lang.Cloneable, Filter, java.util.Map, java.io.Serializable

public class StringFilter

extends java.util.Hashtable

implements Filter

Stupid implementation of Filter interface to demonstrate how easy
it is to create your own filters. This should NOT be used in/for
anything real. Anyone want to implement a regex filter?
