public class NumberedDFSDiscoverTimeIterator<T>
extends DFSDiscoverTimeIterator<T>

This class implements depth-first search over a NumberedGraph, return an enumeration of the nodes of the graph in order of increasing discover time. This class follows the outNodes of the graph nodes to define the graph, but this behavior can be changed by overriding the getConnected method.
