Access timeline functions from inside a class

[lastMohican]

As above is there a way to access any function written inside main timeline from a class ?

for example:
main timeline frame 4:

function foo()
{
    trace("foo");
} 

Class

package{

import flash.display.*;

public class SomeDisplayObjectClass extends MovieClip
{

    public function SomeDisplayObjectClass()
    {
    stage.foo(); /*error 1061: Call to a possibly undefined method foo through     a reference with static type flash.display:Stage.*/

    }

}

} 

Is there any other way to do this?

I am not exactly sure what you are trying to achieve but you can call a function after a tween using the onMotionFinished code. This helps play or toggle a function in the main timeline. Hope this helps out at least at a remote level.
