UML diagram for generic types?

Question

Suppose I have the following code:

class A<U> {}
class B<T> : A <B<B<T>>> {}

How such types can be represented in UML class diagram?

In pure UML, I would use UML Template take a look at the section 17.4 of UML2.4.1 specification. You can also take a look at this thread dealing with Java generic. But if you want to generate C# code from your UML model, the UML specification would depend of the used tool and its generator...

For example under Modelio, class A<U> {} will be represented as

What about `class B : A >> {}`? Shall we define template inside template that refers to A? – user2341923 Oct 29 '13 at 12:50
Honestly I did not see how possible to model your example if your 'three B' are the same unique class... – Red Beard Oct 29 '13 at 13:30
