How to draw a UML class diagram for code based on a C ++ template (e.g. TMP)

Question

I am drawing UML for C ++, as the UML distilled book teaches.

Before learning Template Programming, a book was enough. But while I'm studying Template Programming, including Template Meta Programming, I finally met this problem.

• Are there any known methods for instantiating templates?
• Any better way to express an instance of templates?

From this page you can find the UML diagram I drew for

will inherit / namedtmpl.cpp

This is an example book, C ++ templates are a complete guide. If you could explain it as an example, it would be better.

I am using StarUML.
