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:
java.io.Serializable, java.lang.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.
