getDistanceTo

public abstract long getDistanceTo(Location location)

The distance's unit of measurement depends on the VehicleRoutingSolution's DistanceType. It can be in miles or km, but for most cases it's in the TSPLIB's unit of measurement.

Parameters:

location - never null

Returns:

a positive number, the distance multiplied by 1000 to avoid floating point arithmetic rounding errors

getAirDistanceDoubleTo

public double getAirDistanceDoubleTo(Location location)

getAngle

public double getAngle(Location location)

The angle relative to the direction EAST.

Parameters:

location - never null

Returns:

in Cartesian coordinates

toString

public String toString()

Overrides:

toString in class AbstractPersistable
