public class TraversalCheckingVisitor
extends AbstractPicoVisitor

Concrete implementation of Visitor which simply checks traversals. This can be a useful class for other Visitor implementations to extend, as it provides a default implementation in case you one is only interested in one PicoVisitor type. Example:

 PicoContainer container = new DefaultPicoContainer();
 PicoContainer child = container.makeChildContainer();

 final List allContainers = new ArrayList();

 PicoVisitor visitor = new TraversalCheckingVisitor() {
     public void visitContainer(PicoContainer pico) {
         super.visitContainer(pico);  //Calls checkTraversal for us.
         allContainers.add(pico);
     }
 }
