public interface Vertex
extends java.lang.Comparable
DijkstraAlgorithm
. If you want to represent a city,
you can do "public class City implements Vertex". The purpose of this interface is to make
sure the Vertex implementation implements the Comparable interface so the sorting order is
well-defined even when two vertices have the same penalty/distance from an origin point.
Therefore, make sure you implement the compareTo(Object)
and
equals(Object)
