public class FindPathDFS
extends DFS
This class specializes DFS to determine, given a vertex v, if there is a path from the start vertex to v in the connected component of the start vertex. The algorithm returns an enumeration of vertices in the path, or an empty enumeration if the path does not exist.

o FindPathDFS()

Method Index

o execute(InspectableGraph, Vertex, Object)
Runs the depth first search algorithm on a graph.
o finishVisit(Vertex)
Called when the search has finished with the vertex.
o isDone()
Tests if the depth first search is done.
o startVisit(Vertex)
Called when a vertex is visited.

Variables

o path 
 protected Sequence path

Methods

o execute 
 public Object execute(InspectableGraph g,
                       Vertex start,
                       Object info)
Runs the depth first search algorithm on a graph.

Overrides:
execute in class DFS
o startVisit 
 protected void startVisit(Vertex v)
Called when a vertex is visited.

Overrides:

o finishVisit 
 protected void finishVisit(Vertex v)
Called when the search has finished with the vertex.

Overrides:
