All Implemented Interfaces:

GraphWalker

public class SimpleGraphWalker

extends java.lang.Object

implements GraphWalker

A simple implentation of GraphWalker that decorates a GraphVisitor.

Constructor Summary

SimpleGraphWalker(GraphVisitor visitor)
Creates a GraphWalker from a preexising GraphVisitor

Method Summary

void	finish() Does nothing.
void	init(GraphComponent element) Resets visited flag and counter.
boolean	isVisited(GraphComponent element) Returns the visited flag of the graph component.
int	visit(GraphComponent element, GraphTraversal traversal) Sets the visted flag, and passes the element on to underlying visitor.
