Class DefaultDirectedWeightedGraph<V,E>

java.lang.Object

org.jgrapht.graph.AbstractGraph<V,E>

org.jgrapht.graph.AbstractBaseGraph<V,E>

org.jgrapht.graph.DefaultDirectedGraph<V,E>

org.jgrapht.graph.DefaultDirectedWeightedGraph<V,E>

Type Parameters:

V - the graph vertex type

E - the graph edge type

All Implemented Interfaces:

Serializable, Cloneable, Graph<V,E>

public class DefaultDirectedWeightedGraph<V,E>
extends DefaultDirectedGraph<V,E>

The default implementation of a directed weighted graph. A default directed weighted graph is a non-simple directed graph in which multiple (parallel) edges between any two vertices are not permitted, but loops are. The graph has weights on its edges.
