GraphHopperRoutingService

class GraphHopperRoutingService @JvmOverloads constructor(map: URL, cacheDirectory: Path = DEFAULT_CACHE_DIRECTORY, val defaultOptions: GraphHopperOptions = Companion.defaultOptions) : RoutingService<GeoPosition, GraphHopperOptions> (source)

RoutingService implementation based on GraphHopper.

The routing graph of map is imported once and stored in a FileSystemDirectoryCache rooted in cacheDirectory, where later instances (also in other simulations) load it from.

Constructors

@JvmOverloads

constructor(map: URL, cacheDirectory: Path = DEFAULT_CACHE_DIRECTORY, defaultOptions: GraphHopperOptions = Companion.defaultOptions)

Types

Companion

object Companion

Default values for GraphHopper.

Properties

defaultOptions

open override val defaultOptions: GraphHopperOptions

The default set of options.

Functions

allowedPointClosestTo

open fun allowedPointClosestTo(position: GeoPosition): GeoPosition?

Retrieves (if available) the valid point closest to position, using the default options.

open override fun allowedPointClosestTo(position: GeoPosition, options: GraphHopperOptions): GeoPosition?

Retrieves (if available) the valid point closest to position with the provided options. For instance, this method could be used to find the pedestrian-allowed road closer to a highway.

parseOptions

open override fun parseOptions(options: String): GraphHopperOptions

Creates a set of options from the provided string.

route

open fun route(from: GeoPosition, to: GeoPosition): Route<GeoPosition>

Computes a Route a P another.

open fun route(from: GeoPosition, to: GeoPosition, options: String): Route<GeoPosition>

open override fun route(from: GeoPosition, to: GeoPosition, options: GraphHopperOptions): Route<GeoPosition>

Computes a Route a P another, honoring the provided set of navigation options.
