I'm very new to AS3.

I'd like to give certain objects in a MC the "class" ( meaning css like class ) rollover. So I can automatically create a rollOver that fades up all objects declared as rollOver objects. 

jQuery exmaple

```
$("#myObject .rollOverObject").animate(...);

```

What would be the best way to achieve something like that in AS3?

Thank you in advance and best regards.
