mxICostFunction (mxGraph 4.2.2 API Specification)

All Known Implementing Classes:

mxConstantCostFunction, mxConstCostFunction, mxCostFunction, mxDistanceCostFunction, mxDoubleValCostFunction, mxGeneratorConstFunction, mxGeneratorFunction, mxGeneratorRandomFunction, mxGeneratorRandomIntFunction
```
public interface mxICostFunction
```
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 mxDistanceCostFunction(graph) or new mxConstantCostFunction(1).
