Class RoadSegmentLocation

java.lang.Object

org.optaplanner.examples.common.domain.AbstractPersistable

org.optaplanner.examples.vehiclerouting.domain.location.Location

org.optaplanner.examples.vehiclerouting.domain.location.segmented.RoadSegmentLocation

All Implemented Interfaces:

Serializable, Comparable<AbstractPersistable>

public class RoadSegmentLocation
extends Location

Like RoadLocation, but for high scale problems to avoid the memory issue of keeping the entire cost matrix in memory. Used with DistanceType.SEGMENTED_ROAD_DISTANCE.

getDistanceTo

public long getDistanceTo(Location location)

Description copied from class: 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.

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

getDistanceDouble

public Double getDistanceDouble(RoadSegmentLocation location)

getShortestDistanceDoubleThroughHubs

protected double getShortestDistanceDoubleThroughHubs(RoadSegmentLocation location)
