DescendingVisitor (Apache Commons BCEL 6.4.1 API)

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.
