RouteRefreshOptions

The options available for refreshing the current primary NavigationRoute, as well as the alternatives. Each refresh will update:

• RouteLeg.annotation

• RouteLeg.incidents

• RouteLeg.closures

• duration fields

This includes traffic congestion and estimated travel time. Make sure that RouteOptions.enableRefresh is true to take advantage of this feature.

In case of a route refresh failing for 3 * intervalMillis (default is 15 min), expired incidents and congestion annotations will be removed from the route in order to avoid presenting non-critical, outdated information. Closures are not cleared automatically, only upon information from a successful refresh.
