OrderedSparseMultigraph

public OrderedSparseMultigraph()

Creates a new instance.

Method Details

getFactory

public static <V,E>
com.google.common.base.Supplier<Graph<V,E>> getFactory()

Type Parameters:

V - the vertex type for the graph Supplier

E - the edge type for the graph Supplier

Returns:

a Supplier that creates an instance of this graph type.

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 SparseMultigraph<V,E>

Parameters:

vertex - the vertex to add

Returns:

true if the add is successful, and false otherwise

getPredecessors

public Collection<V> getPredecessors(V vertex)

Description copied from interface: Graph

Returns a Collection view of the predecessors of vertex in this graph. A predecessor of vertex is defined as a vertex v which is connected to vertex by an edge e, where e is an outgoing edge of v and an incoming edge of vertex.

Specified by:

getPredecessors in interface Graph<V,E>

Specified by:

getPredecessors in interface Hypergraph<V,E>

Overrides:

getPredecessors in class SparseMultigraph<V,E>

Parameters:

vertex - the vertex whose predecessors are to be returned

Returns:

a Collection view of the predecessors of vertex in this graph

getSuccessors

public Collection<V> getSuccessors(V vertex)

Description copied from interface: Graph

Returns a Collection view of the successors of vertex in this graph. A successor of vertex is defined as a vertex v which is connected to vertex by an edge e, where e is an incoming edge of v and an outgoing edge of vertex.

Specified by:

getSuccessors in interface Graph<V,E>

Specified by:

getSuccessors in interface Hypergraph<V,E>

Overrides:

getSuccessors in class SparseMultigraph<V,E>

Parameters:

vertex - the vertex whose predecessors are to be returned

Returns:

a Collection view of the successors of vertex in this graph

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 SparseMultigraph<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

getIncidentEdges

public Collection<E> getIncidentEdges(V vertex)

Description copied from interface: Hypergraph

Returns the collection of edges in this graph which are connected to vertex.

Specified by:

getIncidentEdges in interface Hypergraph<V,E>

Overrides:

getIncidentEdges in class SparseMultigraph<V,E>

Parameters:

vertex - the vertex whose incident edges are to be returned

Returns:

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