Class Multigraph<V,E>

java.lang.Object

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

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

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

Type Parameters:

V - the graph vertex type

E - the graph edge type

All Implemented Interfaces:

Serializable, Cloneable, Graph<V,E>

Direct Known Subclasses:

WeightedMultigraph

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

A multigraph. A multigraph is a non-simple undirected graph in which no loops are permitted, but multiple (parallel) edges between any two vertices are. If you're unsure about multigraphs, see: http://mathworld.wolfram.com/Multigraph.html.

Multigraph

public Multigraph(Class<? extends E> edgeClass)

Creates a new graph.

Parameters:

edgeClass - class on which to base the edge supplier

Multigraph

public Multigraph(Supplier<V> vertexSupplier,
 Supplier<E> edgeSupplier,
 boolean weighted)

Creates a new graph.

Parameters:

vertexSupplier - the vertex supplier, can be null

edgeSupplier - the edge supplier, can be null

weighted - whether the graph is weighted or not
