Method Detail

setType

public VehicleImpl.Builder setType(VehicleType type)

Sets the VehicleType.

Parameters:

type - the type to be set

Returns:

this builder

Throws:

IllegalArgumentException - if type is null

setReturnToDepot

public VehicleImpl.Builder setReturnToDepot(boolean returnToDepot)

Sets the flag whether the vehicle must return to depot or not.

If returnToDepot is true, the vehicle must return to specified end-location. If you omit specifying the end-location, vehicle returns to start-location (that must to be set). If you specify it, it returns to specified end-location.

If returnToDepot is false, the end-location of the vehicle is endogenous.

Parameters:

returnToDepot - true if vehicle need to return to depot, otherwise false

Returns:

this builder

setStartLocation

public VehicleImpl.Builder setStartLocation(Location startLocation)

Sets start location.

Parameters:

startLocation - start location

Returns:

start location

setEndLocation

public VehicleImpl.Builder setEndLocation(Location endLocation)

setEarliestStart

public VehicleImpl.Builder setEarliestStart(double earliest_startTime)

Sets earliest-start of vehicle which should be the lower bound of the vehicle's departure times.

Parameters:

earliest_startTime - the earliest start time / departure time of the vehicle at its start location

Returns:

this builder

setLatestArrival

public VehicleImpl.Builder setLatestArrival(double latest_arrTime)

Sets the latest arrival at vehicle's end-location which is the upper bound of the vehicle's arrival times.

Parameters:

latest_arrTime - the latest arrival time of the vehicle at its end location

Returns:

this builder

addSkill

public VehicleImpl.Builder addSkill(String skill)

build

public VehicleImpl build()

Builds and returns the vehicle.

if VehicleType is not set, default vehicle-type is set with id="default" and capacity=0

if startLocationId || locationId is null (=> startLocationCoordinate || locationCoordinate must be set) then startLocationId=startLocationCoordinate.toString() and locationId=locationCoordinate.toString() [coord.toString() --> [x=x_val][y=y_val])

if endLocationId is null and endLocationCoordinate is set then endLocationId=endLocationCoordinate.toString()

if endLocationId==null AND endLocationCoordinate==null then endLocationId=startLocationId AND endLocationCoord=startLocationCoord Thus endLocationId can never be null even returnToDepot is false.

Returns:

vehicle

Throws:

IllegalArgumentException - if both locationId and locationCoord is not set or (endLocationCoord!=null AND returnToDepot=false) or (endLocationId!=null AND returnToDepot=false)

newInstance

public static VehicleImpl.Builder newInstance(String vehicleId)

Returns new instance of vehicle builder.

Parameters:

vehicleId - the id of the vehicle which must be a unique identifier among all vehicles

Returns:

vehicle builder

addSkills
