Apply filter for all functions inside a controller

Hi! I created a filter for auth but i would like apply this filter for all methods inside the controller.

This is my routes:

PHP Code:

$routes->get('articles', 'Articles',['filter' => 'auth']);
$routes->get('articles/(:any)', 'Articles',['filter' => 'auth']); 


Is possible do it with a unique route? Someone can help me please? Thanks.
