Display generics in method signatures

I have a parameterised method.

getMyList(): ArrayList

To put in the , I just edit the method manually.

Is this the best way to do this?

Also, I would like to show this method in two different class diagrams. A sort of before and after generics view of the method. One with the generified version and one with the ungenerified version.

So in the former I wish:

getMyList(): ArrayList

and in the latter I just want:

getMyList(): ArrayList

I have to have them both the same. Any ideas here?
