Class VehicleRoutingTransportCostsMatrix

java.lang.Object
  util.VehicleRoutingTransportCostsMatrix

All Implemented Interfaces:

BackwardTransportCost, BackwardTransportTime, ForwardTransportCost, ForwardTransportTime, TransportCost, TransportTime, VehicleRoutingTransportCosts

public class VehicleRoutingTransportCostsMatrix
extends java.lang.Object
implements VehicleRoutingTransportCosts

CostMatrix that allows pre-compiled time and distance-matrices to be considered as VehicleRoutingRoutingCosts in the VehicleRoutingProblem.

Note that you can also use it with distance matrix only (or time matrix). But ones you set a particular distance, this expects distance-entries for all relations. This counts also for a particular time. If the method getTransportCosts(...) is then invoked for a relation, where no distance can be found, an IllegalStateException will be thrown. Thus if you want to only use distances only, do not use addTransportTime(...).
