Direct Known Subclasses:

DirectedWeightedMultigraph

public class DirectedMultigraph<V,E>
extends AbstractBaseGraph<V,E>

A directed multigraph. A directed multigraph is a non-simple directed graph in which no loops are permitted, but multiple (parallel) edges between any two vertices are.

Constructor Detail

DirectedMultigraph

public DirectedMultigraph(java.lang.Class<? extends E> edgeClass)

Creates a new graph.

Parameters:

edgeClass - class on which to base the edge supplier

DirectedMultigraph

public DirectedMultigraph(java.util.function.Supplier<V> vertexSupplier,
