Method Detail

copyOf

public static VehicleRoute copyOf(VehicleRoute route)

Returns a deep copy of this vehicleRoute.

Parameters:

route - route to copy

Returns:

copied route

Throws:

IllegalArgumentException - if route is null

emptyRoute

public static VehicleRoute emptyRoute()

Returns an empty route.

An empty route has an empty list of tour-activities, no driver (DriverImpl.noDriver()) and no vehicle (VehicleImpl.createNoVehicle()).

Returns:

empty route

getActivities

public List<TourActivity> getActivities()

Returns an unmodifiable list of activities on this route (without start/end).

Returns:

list of tourActivities

getTourActivities

public TourActivities getTourActivities()

Returns TourActivities.

Returns:

TourActivities

getVehicle

public Vehicle getVehicle()

Returns the vehicle operating this route.

Returns:

Vehicle

getDriver

public Driver getDriver()

Returns the driver operating this route.

Returns:

Driver

setVehicleAndDepartureTime

public void setVehicleAndDepartureTime(Vehicle vehicle,
                                       double vehicleDepTime)

Sets the vehicle and its departureTime from vehicle.getStartLocationId().

This implies the following:
if start and end are null, new start and end activities are created.

startActivity is initialized with the start-location of the specified vehicle (vehicle.getStartLocationId()). the time-window of this activity is initialized such that [startActivity.getTheoreticalEarliestOperationStartTime() = vehicle.getEarliestDeparture()][startActivity.getTheoreticalLatestOperationStartTime() = vehicle.getLatestArrival()]

endActivity is initialized with the end-location of the specified vehicle (vehicle.getEndLocationId()). The time-window of the endActivity is initialized such that [endActivity.getTheoreticalEarliestOperationStartTime() = vehicle.getEarliestDeparture()][endActivity.getTheoreticalLatestOperationStartTime() = vehicle.getLatestArrival()]

startActivity.endTime (startActivity.getEndTime()) is set to max{vehicle.getEarliestDeparture(), vehicleDepTime}. thus, vehicle.getEarliestDeparture() is a physical constraint that has to be met.

Parameters:

vehicle - to be employed

vehicleDepTime - of employed vehicle

getDepartureTime

public double getDepartureTime()

Returns the departureTime of this vehicle in this route.

Returns:

departureTime

Throws:

IllegalArgumentException - if start is null

isEmpty

public boolean isEmpty()

Returns tour if tour-activity-sequence is empty, i.e. to activity on the tour yet.

Returns:

true if route is empty

getStart

public Start getStart()

Returns start-activity of this route.

Returns:

start

getEnd

public End getEnd()

Returns end-activity of this route.

Returns:

end

toString

public String toString()

Overrides:

toString in class Object
