Method Detail

getVertices

public Set<V> getVertices()

Description copied from interface: MultiGraph

Gets the set of vertices for this graph.

Specified by:

getVertices in interface MultiGraph<V,E extends Edge<V>,EX extends Exception>

getEdgesFrom

public Set<E> getEdgesFrom(V from)

Description copied from interface: Graph

Gets the edges from the provided vertex. The vertex must be part of this graph, and the results are undefined if it is not. A graph only allows unique combinations of from and to vertices.

Specified by:

getEdgesFrom in interface Graph<V,E extends Edge<V>,EX extends Exception>

Specified by:

getEdgesFrom in interface MultiGraph<V,E extends Edge<V>,EX extends Exception>

getEdgesTo

public Set<E> getEdgesTo(V to)

Description copied from interface: SymmetricGraph

Gets the edges to the provided vertex. The vertex must be part of this graph, and the results are undefined if it is not. A graph only allows unique combinations of from and to vertices.

Specified by:

getEdgesTo in interface SymmetricGraph<V,E extends Edge<V>,EX extends Exception>

Specified by:

getEdgesTo in interface SymmetricMultiGraph<V,E extends Edge<V>,EX extends Exception>
