Method Detail

addPathData

public ShortestPathList addPathData(PathData data)

Add the new path to the list of shortest paths, if it is indeed a shortest path

Parameters:

data - A shortest path message

Returns:

The updated ShortestPathList, or null if no update was made.

addPartialDep

public PartialDependency addPartialDep(String src,
                              double dep,
                              int successorDelta)

Updates pair dependency data

Parameters:

src - The source vertex

dep - The partial dependency value of this vertex on the source

successorDelta - The change in number of successors remaining to accumulate. -1 if accumulating a dependency, 1 if adding a successor.

Returns:

the PartialDependency object that was updated.
