This implementation uses the '_controller' request attribute to determine the controller to execute.
Methods
| __construct(LoggerInterface $logger = null) | ||
| callable|false | getController(Request $request) Returns the Controller instance associated with a Request. | |
| callable | createController(string $controller) Returns a callable for the given controller. | |
| object | instantiateController(string $class) Returns an instantiated controller. |
Details
__construct(LoggerInterface $logger = null)
Parameters
| LoggerInterface | $logger |
callable|false getController(Request $request)
Returns the Controller instance associated with a 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.
Parameters

Return Value
| callable|false | A PHP callable representing the Controller, or false if this resolver is not able to determine the controller |
Exceptions
| LogicException | If a controller was found based on the request but it is not callable |

Parameters
| string | $controller | A Controller string |
Return Value
| callable | A PHP callable |
protected object instantiateController(string $class)
Returns an instantiated controller.
Parameters
| string | $class | A class name |
