Class DefaultDirectedGraph<V,E>

java.lang.Object

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

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

org.jgrapht.graph.DefaultDirectedGraph<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:

DefaultDirectedWeightedGraph

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

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

Constructor Details

DefaultDirectedGraph

public DefaultDirectedGraph(Class<? extends E> edgeClass)

Creates a new graph.

Parameters:

edgeClass - class on which to base the edge supplier

DefaultDirectedGraph

public DefaultDirectedGraph(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
