Class NotClassFilter

java.lang.Object
  org.clapper.util.classutil.NotClassFilter

All Implemented Interfaces:

ClassFilter

public class NotClassFilter
extends java.lang.Object
implements ClassFilter

NotClassFilter is a ClassFilter that wraps another ClassFilter and negates the sense of the wrapped filter's accept() method. This class conceptually provides a logical "NOT" operator for class name filters. For example, the following code fragment will create a filter that finds all classes that are not interfaces.

 NotClassFilter filter = new NotClassFilter (new InterfaceOnlyClassFilter());
