I am having a hard time building a UML model that uses template elements.
For instance, how should I ago about modeling in UML a class equivalent
to this Java code:
class List<T> {
public void add(T o) {...}
public T get(int pos) {...}
}
and then bind that template with class Account, generating a type that
is a list of accounts?
I believe this can be done in EMF, but can it be done if modeling is
done in UML2? How?
I am still going through the specs for Templates (section 17.5), but so
far it is not clear if I can do it in UML2. I have built the model
attached, created a genmodel from it, but the resulting ECore model
treats the template parameter class as a regular class. Can anyone see
what I am doing wrong/missing?
Thanks,
Rafael
