Relationship Matrix , Requirements and Instances

[ChrisBD]

Okay, using Version 8
If you have a number of requirements that are realized by ClassA.
You create an instance of ClassA => :ClassA

If you go to the relationship matrix it is possible to see that the requirements are realized by ClassA.

Should it be possible to see that these requirements are also met by :ClassA instance?

Hi Chris,

UML isn't very good in specifying such transitive relationships.  For example, it's my contention that if I specialize an item, I should inherit its stereotypes - but UML doesn't consider this.

I agree that a non-canonical (derived) relationship exists between the instance and the items related to the Classifier.

EA doesn't support this functionality which is understandable, in the circumstances.  You'll have to materialize the derived relationship yourself.

HTH,
Paolo

It's not so much specialization that I was thinking of, but actual instance creation.

Hi Chris,

yes, I understand that but what I was trying to show is that this issue is one of a more general class of problem - transitive relationships.
