Constructor Detail

UndirectedOrderedSparseMultigraph

public UndirectedOrderedSparseMultigraph()

Creates a new instance.

Method Detail

getFactory

public static <V,E> org.apache.commons.collections15.Factory<UndirectedGraph<V,E>> getFactory()

Returns a Factory that creates an instance of this graph type.

Type Parameters:

V - the vertex type for the graph factory

E - the edge type for the graph factory

addVertex

public boolean addVertex(V vertex)

Description copied from interface: Hypergraph

Adds vertex to this graph. Fails if vertex is null or already in the graph.

Specified by:

addVertex in interface Hypergraph<V,E>

Overrides:

addVertex in class UndirectedSparseMultigraph<V,E>

Parameters:

vertex - the vertex to add

Returns:

true if the add is successful, and false otherwise

getNeighbors

public Collection<V> getNeighbors(V vertex)

Description copied from interface: Hypergraph

Returns the collection of vertices which are connected to vertex via any edges in this graph. If vertex is connected to itself with a self-loop, then it will be included in the collection returned.

Specified by:

getNeighbors in interface Hypergraph<V,E>

Overrides:

getNeighbors in class UndirectedSparseMultigraph<V,E>

Parameters:

vertex - the vertex whose neighbors are to be returned

Returns:

the collection of vertices which are connected to vertex, or null if vertex is not present
