Package org.jgrapht.graph.guava

Class MutableNetworkAdapter<V,E>

java.lang.Object

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

org.jgrapht.graph.guava.BaseNetworkAdapter<V,E,com.google.common.graph.MutableNetwork<V,E>>

org.jgrapht.graph.guava.MutableNetworkAdapter<V,E>

Type Parameters:

V - the graph vertex type

E - the graph edge type

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, org.jgrapht.Graph<V,E>

public class MutableNetworkAdapter<V,E>
extends BaseNetworkAdapter<V,E,com.google.common.graph.MutableNetwork<V,E>>
implements org.jgrapht.Graph<V,E>, java.lang.Cloneable, java.io.Serializable

A graph adapter class using Guava's MutableNetwork.

Changes in the adapter such as adding or removing vertices and edges are reflected in the underlying network. Example usage:

 MutableNetwork<String, DefaultEdge> mutableNetwork =
     NetworkBuilder.directed().allowsParallelEdges(true).allowsSelfLoops(true).build();
 
 Graph<String, DefaultEdge> graph = new MutableNetworkAdapter<>(
     mutableNetwork, SupplierUtil.createStringSupplier(), SupplierUtil.DEFAULT_EDGE_SUPPLIER);
 
 graph.addVertex("v1");
 
 System.out.println(mutableNetwork.nodes().contains("v1")); // outputs true
