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 Details

    • 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
