abstract class RouteReuseStrategy {
  abstract shouldDetach(route: ActivatedRouteSnapshot): boolean
  abstract store(route: ActivatedRouteSnapshot, handle: DetachedRouteHandle): void
  abstract shouldAttach(route: ActivatedRouteSnapshot): boolean
  abstract retrieve(route: ActivatedRouteSnapshot): DetachedRouteHandle | null
  abstract shouldReuseRoute(future: ActivatedRouteSnapshot, curr: ActivatedRouteSnapshot): boolean
}

abstract shouldDetach(route: ActivatedRouteSnapshot): boolean Parameters route ActivatedRouteSnapshot Returns boolean

store()

abstract shouldAttach(route: ActivatedRouteSnapshot): boolean Parameters route ActivatedRouteSnapshot Returns boolean

retrieve()
Retrieves the previously stored route
abstract retrieve(route: ActivatedRouteSnapshot): DetachedRouteHandle | null Parameters route ActivatedRouteSnapshot Returns DetachedRouteHandle | null

shouldReuseRoute()
Determines if a route should be reused
abstract shouldReuseRoute(future: ActivatedRouteSnapshot, curr: ActivatedRouteSnapshot): boolean Parameters future ActivatedRouteSnapshot curr ActivatedRouteSnapshot Returns boolean
