RoadGraph Class Reference
RoadGraph
public final class RoadGraphRoadGraph provides methods to get edge shape (e.g. ElectronicHorizon.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 PassiveLocationDataSource.roadGraph property.
