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

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() { }
