Class DescendingVisitor

java.lang.Object
  org.apache.bcel.classfile.DescendingVisitor

All Implemented Interfaces:

Visitor

public class DescendingVisitor
extends 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.
