extends java.lang.Object
implements ClassFilter

ClassModifiersClassFilter is a ClassFilter that matches class names that (a) can be loaded and (b) match a set of class modifiers (as defined by the constants in the java.lang.reflect.Modifier class). For instance, the the following code fragment defines a filter that will match only public final classes:

 import java.lang.reflect.Modifier;

 ...

 ClassFilter = new ClassModifiersClassFilter (Modifier.PUBLIC | Modifier.FINAL);
 

This class relies on the pool of classes read by a ClassFinder; it's not really useful by itself.
