register_activation_hook for multiple functions

Question

I have created a plugin where I want to call two different functions on activation.

Is there a best way to do this?

Should I use register_activation_hook twice? As in:

register_activation_hook( __FILE__, 'function_1' );
register_activation_hook( __FILE__, 'function_1' );

Or call the two functions from within an activation function, as in:

register_activation_hook( __FILE__, 'my_activation_function' );
function my_activation_function () {

    function_1();
    function_2();

}

Any ideas? Thanks.

My approach to this would be to have a start_activation() method that calls the other methods.

register_activation_hook( __FILE__, array( 'my_plugin_loader', 'start_activation' ) );

class my_plugin_loader {
    function start_activation() {
        $this->func1(); // or self::func1();
        $this->func2(); //    self::func2(); for static methods
     }
     function func1() {
         // do stuff
     }
     function func2() {
         // do other stuff
     }
 }

I'm not saying it is the "right" way, just how I would approach it.
