All Implemented Interfaces:

ClassFilter

public class RegexClassFilter
extends java.lang.Object
implements ClassFilter

RegexClassFilter is a ClassFilter that matches class names using a regular expression. Multiple regular expression filters can be combined using AndClassFilter and/or OrClassFilter objects.

This class does not have to load the classes it's filtering; it matches on the class name only.

RegexClassFilter uses the java.util.regex regular expression classes.
