Electronic Horizon

Defines options for emitting Notification.Name.electronicHorizonDidUpdatePosition, Notification.Name.electronicHorizonDidEnterRoadObject, and Notification.Name.electronicHorizonDidExitRoadObject notifications while a RouteController or PassiveLocationManager is active.

RoadGraph provides methods to get edge shape (e.g. RoadGraph.Edge) and metadata.

You do not create a RoadGraph object manually. Instead, observe the Notification.Name.electronicHorizonDidUpdatePosition notification to obtain edge identifiers and get more details about the edges using the RouteController.roadGraph or PassiveLocationManager.roadGraph property.

Identifies a road object according to one of two OpenLR standards.

Describes the relationship between the road object and the direction of a referenced line. The road object may be directed in the same direction as the line, against that direction, both directions, or the direction of the road object might be unknown.

A human-readable name or route reference code that identifies a road.

Describes the object on the road. There are two sources of road objects: active route and the electronic horizon.

Contains information about distance to the road object of a concrete type/shape (gantry, polygon, line, point etc.).

Provides methods for road object matching.

Matching results are delivered asynchronously via a delegate. In case of error (if there are no tiles in the cache, decoding failed, etc.) the object won’t be matched.

Stores and provides access to metadata about road objects.

You do not create a RoadObjectStore object manually. Instead, use the RouteController.roadObjectStore or PassiveLocationManager.roadObjectStore to access the currently active road object store.

RoadObjectMatcher delegate.

RoadObjectStore delegate

An error that occures during road object matching.
