I have a class (DataType) that I've written that is intended to be used in an ArrayCollection of these objects (DataTypes). I would like to guarantee that this ArrayCollection can only be populated with objects of the DataType class.
My initial thought was to extended the ArrayCollection class in the DataTypes class, then override the addItem() method and change the item:Object argument to item:CustomObject (which extends Object). Evidently this isn't permissible in Flex (we're still using Flex 2 here). Are there any best practices surrounding this task? Can anyone offer some advice on how I should go about ensuring that the objects added to this ArrayCollection are objects of my custom class? Thanks in advance.
