Class Path<Vertex,Distance>

java.lang.Object
dsa.lab10.base.Path<Vertex,Distance>
Type Parameters:
Vertex - the vertex type
Distance - the distance measure type
public class Path<Vertex,Distance> extends Object
Information about a path (of zero or more edges) from some source to some target vertex.

Contains the previous vertex visited in the path from source to target, and some measure of the total distance from the source to the target.

The idea is that there will be other such Path objects giving information about any previous steps in the path (e.g. how to get to the previous vertex).
