Interface JGraphCostFunction

All Known Implementing Classes:

JGraphConstantCostFunction, JGraphDistanceCostFunction

public interface JGraphCostFunction

The cost function takes a cell and returns it's cost as a double. Two typical examples of cost functions are the euclidian length of edges or a constant number for each edge. To use one of the built-in cost functions, use either new JGraphDistanceCostFunction(graph.getGraphLayoutCache()) or new JGraphConstantCostFunction(1).
