JunctionViewLaneAssistance (API Reference)
Class JunctionViewLaneAssistance
A class that provides lane assistance information for the next complex junction
in order to keep following the route. It is recommended to indicate JunctionViewLaneAssistance
and ManeuverViewLaneAssistance separately or to indicate only ManeuverViewLaneAssistance information -
JunctionViewLaneAssistance will recommend all lanes that allow to pass the upcoming complex junction, regardless
if they will lead to the next maneuver or not.
If the location of a maneuver lies on an upcoming complex junction, the recommended lanes will be
the same as the ones from ManeuverViewLaneAssistance.
A junction is recognized as complex only if:
- it is at least a bifurcation;
- it has at least two lanes whose directions do not follow the current route.
In opposition to
ManeuverViewLaneAssistance, notifications are also forwarded when there is no maneuver action occurring at the next complex junction. Therefore,JunctionViewLaneAssistancecan be disjointed from maneuvers. If lane assistance should be used to associate it with upcoming maneuvers, consider to useManeuverViewLaneAssistanceinstead. Note thatManeuverViewLaneAssistancenotifications are synchronized with maneuver events, whereasJunctionViewLaneAssistanceevents are not strictly synchronized with maneuver events.

lanesForNextJunction
A list of lanes on the next complex junction. The lanes are sorted from left to right: The lane at index 0 represents the leftmost lane and the last index represents the rightmost lane. This is valid for right-hand and left-hand driving countries. An empty list means that the complex junction has been passed and that the lane information is not valid anymore. Exactly one event with a non-empty list is delivered before reaching a complex junction and one event with an empty list afterwards.
Note: Lanes going in opposite direction are not included in the list.
