ControllerResolverInterface
interface ControllerResolverInterface
A ControllerResolverInterface implementation knows how to determine the controller to execute based on a Request object.
It can also determine the arguments to pass to the Controller.
A Controller can be any valid PHP callable.
Methods
| callable|false | getController(Request $request) Returns the Controller instance associated with a Request. | |
| array | getArguments(Request $request, callable $controller) Returns the arguments to pass to the controller. |
Details
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
| Request | $request | A Request instance |
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 the controller can't be found |
array getArguments(Request $request, callable $controller)
Returns the arguments to pass to the controller.
Parameters
| Request | $request | A Request instance |
| callable | $controller | A PHP callable |
Return Value
| array | An array of arguments to pass to the controller |
Exceptions
| RuntimeException | When value for argument given is not provided |
