Class RoadLocation

java.lang.Object

org.optaplanner.examples.common.domain.AbstractPersistable

org.optaplanner.examples.tsp.domain.location.Location

org.optaplanner.examples.tsp.domain.location.RoadLocation

All Implemented Interfaces:

Serializable

public class RoadLocation
extends Location

The cost between 2 locations was precalculated on a real road network route. The cost itself might be the distance in km, the travel time, the fuel usage or a weighted function of any of those. Used with DistanceType.ROAD_DISTANCE.

getDistanceTo

public long getDistanceTo(Location location)

Description copied from class: Location

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

Specified by:

getDistanceTo in class Location

Parameters:

location - never null

Returns:

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