Class FastVehicleRoutingTransportCostsMatrix

java.lang.Object

com.graphhopper.jsprit.core.problem.cost.AbstractForwardVehicleRoutingTransportCosts

com.graphhopper.jsprit.core.util.FastVehicleRoutingTransportCostsMatrix

All Implemented Interfaces:

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

public class FastVehicleRoutingTransportCostsMatrix
extends AbstractForwardVehicleRoutingTransportCosts

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

Note that you can also use it with distance matrix only (or time matrix).
