ControllerResolver

class ControllerResolver implements ControllerResolverInterface

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

Request $request

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

protected callable createController(string $controller)

Returns a callable for the given controller.

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

Return Value

object
