Interface GraphMapping<V,E>

Type Parameters:

V - the graph vertex type

E - the graph edge type

All Known Implementing Classes:

DefaultGraphMapping, IsomorphicGraphMapping

public interface GraphMapping<V,E>

GraphMapping represents a bidirectional mapping between two graphs (called graph1 and graph2), which allows the caller to obtain the matching vertex or edge in either direction, from graph1 to graph2, or from graph2 to graph1. It does not have to always be a complete bidirectional mapping (it could return null for some lookups).

Method Detail

getVertexCorrespondence

V getVertexCorrespondence(V vertex,
                          boolean forward)

Gets the mapped value where the key is vertex

Parameters:

vertex - vertex in one of the graphs

forward - if true, uses mapping from graph1 to graph2; if false, use mapping from graph2 to graph1

Returns:

corresponding vertex in other graph, or null if none

getEdgeCorrespondence

E getEdgeCorrespondence(E edge,
                        boolean forward)

Gets the mapped value where the key is edge

Parameters:

edge - edge in one of the graphs

forward - if true, uses mapping from graph1 to graph2; if false, use mapping from graph2 to graph1

Returns:

corresponding edge in other graph, or null if none
