php - Yii Framework : call Controller's function from CAction class -

i want make modular controller separating actions in different class.
problem of actions calling private function of controler.

controller :

class apicontroller extends controller {     public function actions()     {         return array(             'index'=>'application.controllers.api.indexaction',         );     }      ..........      private function _sendresponse($status = 200, $body = '', $content_type = 'text/html')     {         // code     } }   

in indexaction.php tried this, doesn't work :

class indexaction extends caction {     public function run()     {             $this->getcontroller()->_sendresponse(204); //this error     } 

}

the exception

apicontroller , behaviors not have method or closure named "_sendresponse".   

is possible i'm trying do?
missing here?

i looks try access private method out of scope of class. not classes inherit can access private method. try public function _sendresponse()
