using other controller's method

[eluser]thevenin[/eluser]
Hi guys,

I have two controllers: one for admin panel and one for frontend app.
In both places I need a method which will output an array of objects - let's say the method name is "Rankings".

Admin panel controller:

Code:

class Standings extends Controller {

  ....

  function Rankings() {
    //some code
  }

  ....
}

I would like to call this method in my front controller Frontpage:

Code:

class Frontpage extends Controller {

   //is it possible to call it somehow here?
   //or I have to paste the whole method from Standings controller?

}
