KNTrip

INFO

This English reference is based on Directions SDK with UI 1.12.8-hotfix02 (as of 2026-07-24). For the latest version, see the Korean reference.

A class that manages routes. It takes the location information of the origin, destination, and waypoints as input and provides routes by option. You can also check information such as distance, fee, and time for the selected route.

TIP

• The KNTrip class must be created through KNSDK.
• It works with KNGuidance to run route guidance and manage driving information.

Example code — KNTrip

class KNTrip : KNTrip_GuidanceExtension, KNSerializable

Constructor

Example code — Initialization

// <init>
KNTrip()
KNTrip(start: KNPOI, goal: KNPOI, vias: MutableList<KNPOI>?, csId: String?, transId: String)

Properties

Name	Description	Type
start	Origin location information	var start: KNPOI
goal	Destination location information	var goal: KNPOI
vias	Waypoint location information	var vias: MutableList<KNPOI>?
routeConfig	Route configuration information	var routeConfig: KNRouteConfiguration
useMultiRoute	Whether to use multi-route. true : use multi-route, false : do not use multi-route (default: true )	var useMultiRoute: Boolean

Methods

addVia

Adds a waypoint.

fun addVia(via: KNPOI, location: KNLocation): Unit

Parameters

Name	Description
via	Waypoint location information (POI)
location	Location at which to add the waypoint

addVia

Adds a waypoint.

fun addVia(via: KNPOI, idx: Int): Unit

Parameters

Name	Description
via	Waypoint location information
idx	Waypoint order (index). The order is assigned according to the visiting order of the waypoints; a lower index is the waypoint visited first. If the index is larger than the number of registered waypoints, it is treated as the last waypoint.

elapsedCost

Returns the driving fee to the destination (unit: KRW).

fun elapsedCost(): Int

elapsedDist

Returns the driving distance to the destination (unit: m).

fun elapsedDist(): Int

elapsedTime

Returns the driving time to the destination (unit: seconds).

fun elapsedTime(): Int

passedVias

Returns the list of waypoints that have been driven through in the route.

fun passedVias(): List<KNPOI>?

remainCost

Returns the remaining fee to the destination based on the current location (unit: KRW).

fun remainCost(): Int

remainDist

Returns the remaining distance to the destination (unit: m).

fun remainDist(): Int

remainTime

Returns the remaining time to the destination (unit: seconds).

fun remainTime(): Int

removeAllVias

Removes all waypoints.

fun removeAllVias(): Unit

removeViaAtIdx

Removes a specific waypoint.

fun removeViaAtIdx(idx: Int): Unit

Parameters

Name	Description
idx	Waypoint order (index). The order is assigned according to the visiting order of the waypoints; a lower index is the waypoint visited first. If the index is larger than the number of registered waypoints, it is treated as the last waypoint.

routeWithPriority

Requests a route. The requested route is delivered asynchronously.

fun routeWithPriority(priority: KNRoutePriority, avoidOptions: Int, completion: ((KNError?, MutableList<KNRoute>?) -> Unit)?): Unit

Parameters

Name	Description
priority	Item to prioritize during route guidance
avoidOptions	Sections to exclude from the route. Up to two routes can be entered. The main route and the alternative route are entered in order, and the alternative route can be omitted.
completion	Delivers the requested route

setRouteConfig

Reconfigures the route by reflecting changed information when information such as vehicle type, whether a Hi-pass device is installed, or traffic incident information changes.

fun setRouteConfig(routeConfig: KNRouteConfiguration?): Unit

Parameters

Name	Description
routeConfig	Vehicle information

setVias

Sets waypoints in bulk.

fun setVias(vias: List<KNPOI>?): Unit

Parameters

Name	Description
vias	List of waypoint location information
