  +--org.apache.bcel.classfile.DescendingVisitor
All Implemented Interfaces:
Visitor
public class DescendingVisitor
extends java.lang.Object
implements Visitor

Traverses a JavaClass with another Visitor object 'piggy-backed' that is applied to all components of a JavaClass object. I.e. this class supplies the traversal strategy, other classes can make use of it.
