RouteRefreshExtra

Route refresh states. See RouteRefreshStatesObserver.

The state becomes REFRESH_STATE_CANCELED when a route refresh canceled. It occurs when a new set of routes are set, that leads to interrupt route refresh process.

The state becomes REFRESH_STATE_FINISHED_FAILED when a route refresh failed and the route is cleaned up of expired data, see RouteRefreshOptions for details. The state is triggered in case if every single route refresh of a set of the routes is failed.

The state becomes REFRESH_STATE_FINISHED_SUCCESS when the route is successfully refreshed. The state is triggered in case if at least one route is refreshed successfully.

The state becomes REFRESH_STATE_STARTED when route refresh round is started.
