Class VehicleRoutingTransportCostsMatrix

java.lang.Object

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

com.graphhopper.jsprit.core.util.VehicleRoutingTransportCostsMatrix

All Implemented Interfaces:

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

public class VehicleRoutingTransportCostsMatrix
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). 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(...).

Method Detail

getTransportTime

public double getTransportTime(Location from,
                               Location to,
                               double departureTime,
                               Driver driver,
                               Vehicle vehicle)

Specified by:

getTransportTime in interface ForwardTransportTime

Specified by:

getTransportTime in class AbstractForwardVehicleRoutingTransportCosts

getDistance

public double getDistance(String fromId,
                          String toId)

Returns the distance fromId to toId.

Parameters:

fromId - from locationId

toId - to locationId

Returns:

the distance from fromId to toId

Throws:

IllegalStateException - if distance of fromId -> toId is not found

getTransportCost
