All Known Implementing Classes:
wt.visitor.BasicWalker, BFSWalker, DFSWalker, wt.visitor.Navigator
public interface Walker
This interface is responsible for controlling the overall traversal mechanism. It includes a single traverse() method that provides multi-level navigation of associations between Persistable objects. Depth-first traversal is an example of an implementation. It uses a NodeExpander object to do the actual expansion of nodes. It also is responsible for calling the visit methods on the Visitor object as the structure is traversed. If any visit method returns a boolean false value, then that node will not be traversed any further.
