Method Detail

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_INFINITYis 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_INFINITYin case no such path exists
