OfflineRoutingEngine class abstract

Use this class to calculate a route offline from A to B with a number of waypoints in between.

Route calculation is done asynchronously, and requires map data that is available offline. This can be temporarily cached map data or downloaded offline map data stored in the persisted storage via MapDownloader. Note that when using the cache there is a risk of missing data and this may reduce the overall quality of the route or can result in a RoutingError.noRouteFound error.

The resulting route contains various information such as the polyline, route length in meters, estimated time to traverse along the route and maneuver data, but it does not contain traffic information.

Unlike the RoutingEngine (which requires an online connection), this engine allows to use an unlimited number of waypoints.

As an alternative to this engine, consider to use the RoutingEngine for online route calculations to get fresher traffic, maneuver, route handles and street information, and to use a more elaborate algorithms to calculate the fastest route.

For offline bus routing, enable "OFFLINE_BUS_ROUTING" as feature configuration. For more details, please look at SDKOptions. If this feature is not enabled, the engine may not be able to find bus routes.

Note: EV routing is available when calculating a route using the RoutingOptions, by setting the RoutingOptions.evOptions.

Note: Traffic related information is completely excluded. No historic traffic patterns are taking into consideration for the ETA. Currently blocked or closed roads or roads with traffic incident are not considered offline, i.e. the road may pass through such road. Only seasonal road closures are considered based on the departure time, if given. Traffic information is only considered for online route calculation with the RoutingEngine.
