ControllerResolverInterface

interface ControllerResolverInterface

A ControllerResolverInterface implementation knows how to determine the controller to execute based on a Request object.

A Controller can be any valid PHP callable.

Methods

callable|false getController(Request $request)

Returns the Controller instance associated with a Request.

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

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
