Other Structures

BorderCrossingInfo encapsulates a border crossing, specifying crossing region codes.

An electronic horizon is a probable path (or paths) of a vehicle within the routing graph. This structure contains metadata about the underlying edges of the graph for a certain distance in front of the vehicle, thus extending the user’s perspective beyond the “visible” horizon as the vehicle’s position and trajectory change.

During active turn-by-turn navigation, the user-selected route and its metadata influence the path of the electronic horizon determined by RouteController. During passive navigation (free-driving), no route is actively selected, so PassiveLocationDataSource will determine the most probable path from the vehicle’s current location. You can receive notifications about changes in the current state of the electronic horizon by observing the Notification.Name.electronicHorizonDidUpdatePosition, Notification.Name.electronicHorizonDidEnterRoadObject, and Notification.Name.electronicHorizonDidExitRoadObject notifications.

The road network ahead of the user is represented as a tree of edges. Each intersection has outlet edges. In turn, each edge has a probability of transition to another edge, as well as details about the road segment that the edge traverses. You can use these details to influence application behavior based on predicted upcoming conditions.

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

Information about distances related to a road object

Represents location of road object on road graph.

A point object is represented by a single edge whose location has the same fractionFromStart and fractionToEnd.

Specifies the content that a predictive cache fetches and how it fetches the content.

Pass an instance of this class into the NavigationOptions(styles:navigationService:voiceController:topBanner:bottomBanner:predictiveCacheOptions:) initializer or NavigationMapView.enablePredictiveCaching(options:) method.

RouteAlert encapsulates information about various incoming events. Common attributes like location, distance to the event, length and other is provided for each POI, while specific meta data is supplied via alert property.

Tunnel is used for naming incoming tunnels, together with route alerts.
