All Implemented Interfaces:

DependencyVisitor

public class CloningDependencyVisitor
extends Object
implements DependencyVisitor

A dependency visitor that constructs a clone of the visited dependency graph. If such a visitor is passed into a FilteringDependencyVisitor, a sub graph can be created. This class creates shallow clones of the visited dependency nodes but clients can create a subclass and override clone(DependencyNode) to alter the clone process.
