Type Members

  1. type SPMap = Map[VertexId, Int]

    Stores a map from the vertex id of a landmark to the distance to that landmark.

Value Members

  1. def run[VD, ED](graph: Graph[VD, ED], landmarks: Seq[VertexId])(implicit arg0: ClassTag[ED]): Graph[SPMap, ED]

    Computes shortest paths to the given set of landmark vertices.

    Computes shortest paths to the given set of landmark vertices.

    ED

    the edge attribute type (not used in the computation)

    graph

    the graph for which to compute the shortest paths

    landmarks

    the list of landmark vertex ids. Shortest paths will be computed to each landmark.

    returns

    a graph where each vertex attribute is a map containing the shortest-path distance to each reachable landmark vertex.
