Static Methods

addAntiPersistentRoadblockByArea({required GeographicArea area, required DateTime startTime, required DateTime expireTime, required RouteTransportMode transportMode, required String id}) → (TrafficEvent?, GemError): Adds a user-defined persistent anti-area roadblock.
addPersistentRoadblockByArea({required GeographicArea area, required DateTime startTime, required DateTime expireTime, required RouteTransportMode transportMode, required String id}) → (TrafficEvent?, GemError): Adds a user-defined persistent roadblock covering a geographic area.
addPersistentRoadblockByCoordinates({required List<Coordinates> coords, required DateTime startTime, required DateTime expireTime, required RouteTransportMode transportMode, required String id}) → (TrafficEvent?, GemError): Adds a user-defined persistent roadblock using a list of coordinates.
getOnlineServiceRestrictions(Coordinates coords) → Set<TrafficOnlineRestrictions>: Retrieves online traffic service restrictions for a position.
getPersistentRoadblock(String id) → TrafficEvent?: Retrieves a persistent roadblock by its identifier.
getPersistentRoadblockPathPreview({required UserRoadblockPathPreviewCoordinate from, required Coordinates to, required RouteTransportMode transportMode}) → (List<Coordinates>, UserRoadblockPathPreviewCoordinate, GemError): Returns a preview of a persistent roadblock path between two coordinates.
removeAllPersistentRoadblocks() → void: Removes all user-defined persistent roadblocks.
removePersistentRoadblockByCoordinates(Coordinates coords) → GemError: Removes a persistent roadblock identified by its reference coordinate.
removePersistentRoadblockById(String id) → GemError: Removes a previously created persistent roadblock by its identifier.
removeUserRoadblock(TrafficEvent event) → void: Removes a user-defined roadblock, whether persistent or not.
