Objects are all passed by reference, I want to pass a weak reference
back to callers who request items from the cache, much like the
internal implementation must do in some way when
addEventListener(...true) as a weak reference.
For example:
public function getItem( id:String ):Item
{
var item:Item = getItemFromCache(id);
return new WeakReference( item );
}
So that anyone who has obtained an item from cache will not prevent
the object from being garbage collected.
Thanks,
Greg
