Load library/helper/... once on controller

[eluser]Unknown[/eluser]
I want to load library once on controller, without having to declare again load->library in each function.
Can?

Example Current:

Code:

class Blog extends CI_Controller {

public function index()

{
                $this->load->library("xxx");
  echo 'Hello World!';
}

public function comments()
{
                $this->load->library("xxx");
  echo 'Look at this!';
}
}

Example Affter:

Code:

class Blog extends CI_Controller {
        public function ....{
        $this->load->library("xxx");
        }
        
public function index()

{
                
  echo 'Hello World!';
}

public function comments()
{
                
  echo 'Look at this!';
}
}

Aahh and without autoload!
