RE: [flexcoders] cast/convert to a child class?

ArrayCollection does not have any idea what type of elements you put into it. 
You can have an ArrayCollection full of Dog instances, or an ArrayCollection 
full of Cat instances, or an ArrayCollection full of Cats and Dogs (i.e., 
Pets). But all are just ArrayCollections and no casting is required.

You're probably thinking of Vector. vs Vector.. There are indeed 
different types, and one cannot be cast to the other.

If your array references Pet objects, you cannot cast them as Dog() 
because they aren't Dog objects.
If your array references Dog objects, you can cast them as Dog() because 
they are Dog objects.

Dogs are an extension of Pet and a Pet object does not have the class 
attributes (or methods) that a Dog object would.
