Call Util , Configuration methods in a function of AdminController

[jbastarras]

I have a class like this 

 

class AdminOrdersController extends AdmiOrdersControllerCore {

 

public function __construct()

{

 

try {

$accion = $_GET['action'] ;

 

if ($_GET['action']=='validar'){

$this->yourexamplefunction();

}else{

parent::__construct();

$this->_conf = $this->_conf + array(32 => $this->l('text.'));

}

 

}catch(Exception $e){

 

}

parent::__construct();

$this->_conf = $this->_conf + array(32 => $this->l('text'));

 

 

}

 

 

And the function 

 

 

public function yourexamplefunction(){

 

$result = Db::getInstance()->execute('

SELECT id_order

FROM '._DB_PREFIX_.'orders where mark IS NULL 

');

 

 

$module_name = self::config('app')['module_name'];

 

die($module_name );

 

 

And prestashop show me this error 

 

Call to undefined method AdminOrdersController::config() in C:\develop\prestashop\override\controllers\admin\AdminOrdersController.php on line 231

 

 

Why? How include Controllers in my function ?
