  • Method Summary

    Modifier and Type Method Description
    Graph<V,​E> getGraph()
    Returns the graph over which this set of paths is defined.
    GraphPath<V,​E> getPath​(V sink)
    Return the path from the source vertex to the sink vertex.
    V getSourceVertex()
    Returns the single source vertex.
    double getWeight​(V sink)
    Return the weight of the path from the source vertex to the sink vertex.

  • Method Details

    • getGraph

      Graph<V,​E> getGraph()
      Returns the graph over which this set of paths is defined.
      Returns:
      the graph

    • getSourceVertex

      V getSourceVertex()
      Returns the single source vertex.
      Returns:
      the single source vertex

    • getWeight

      double getWeight​(V sink)
      Return the weight of the path from the source vertex to the sink vertex. If no such path exists, Double.POSITIVE_INFINITY is returned. The weight of the path between a vertex and itself is always zero.
      Parameters:
      sink - the sink vertex
      Returns:
      the weight of the path between source and sink vertices or Double.POSITIVE_INFINITY in case no such path exists

    • getPath

      GraphPath<V,​E> getPath​(V sink)
      Return the path from the source vertex to the sink vertex.
      Parameters:
      sink - the sink vertex
      Returns:
      the path from the source vertex to the sink vertex or null if no such path exists
