public AccessManager::check(RouteMatchInterface $route_match, AccountInterface $account = NULL, Request $request = NULL, $return_as_object = FALSE)
Checks a route against applicable access check services.
Determines whether the route is accessible or not.
Parameters
\Drupal\Core\Routing\RouteMatchInterface $route_match: The route match.
\Drupal\Core\Session\AccountInterface $account: (optional) Run access checks for this account. Defaults to the current user.
\Symfony\Component\HttpFoundation\Request $request: Optional, a request. Only supply this parameter when checking the incoming request, do not specify when checking routes on output.
bool $return_as_object: (optional) Defaults to FALSE.
Return value
bool|\Drupal\Core\Access\AccessResultInterface The access result. Returns a boolean if $return_as_object is FALSE (this is the default) and otherwise an AccessResultInterface object.
