Class StringFilter

java.lang.Object

All Implemented Interfaces:

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?
