class ControllerResolver implements ArgumentResolverInterface, ControllerResolverInterface
This implementation uses the '_controller' request attribute to determine the controller to execute and uses the request attributes to determine the controller method arguments.
Methods
| __construct(LoggerInterface $logger = null) | ||
| callable|false | getController(Request $request) Returns the Controller instance associated with a Request. | |
| array | getArguments(Request $request, callable $controller) deprecated Returns the arguments to pass to the controller. |
Details
__construct(LoggerInterface $logger = null)
Parameters
| LoggerInterface | $logger |
callable|false getController(Request $request)

As several resolvers can exist for a single application, a resolver must return false when it is not able to determine the controller.
The resolver must only throw an exception when it should be able to load controller but cannot because of some errors made by the developer.
