costToCross

public double costToCross(java.lang.Object fromNode,
                          java.lang.Object toNode)

The cost to cross an edge.

Specified by:

costToCross in interface GEPathMeter

intCostToCross

public int intCostToCross(java.lang.Object fromNode,
                          java.lang.Object toNode)

The cost to cross an edge.

Specified by:

intCostToCross in interface GEPathMeter

negativeWeightEdges

public boolean negativeWeightEdges()

Returns true if this PathMeter can return negative weight edges, false if not. Shortest path algorithms use this method to trigger the bellman-ford algorithm to detect negative weight cycles. If you're not sure, return true.
