The added filter will be attached to the event manager used by this dispatcher.

dispatch()source public

dispatch( Cake\Network\Request $request , Cake\Network\Response $response )

Dispatches and invokes given Request, handing over control to the involved controller. If the controller is set to autoRender, via Controller::$autoRender, then Dispatcher will render the view.

Actions in CakePHP can be any public method on a controller, that is not declared in Controller. If you want controller methods to be public and in-accessible by URL, then prefix them with a _. For example public function _loadPosts() { } would not be accessible via URL. Private and protected methods are also not accessible via URL.

If no controller of given name can be found, invoke() will throw an exception. If the controller is found, and the action is not found an exception will be thrown.

Parameters

Cake\Network\Request $request

Request object to dispatch.

Cake\Network\Response $response

Response object to put the results of the dispatch into.
