cakephp 2.0 before filter

Question

In CakePHP 2.0 version, I have written something like this in UsersController.php

public function  beforeFilter() {
    parent::beforeFilter();
}

Here, what parent::beforeFilter(); will do?

Answer 1

It performs the parent's beforeFilter() method. In this case, since UsersController extends AppController, it uses AppController's (if existent).
