Hi there,

I'm doing a transformation of a UML diagram .. I need urgently, if any of you could help me, please. My problem is as follows:

Is it possible to pass external parameters to a program ATL and QVR-Relation, eg. x = "ClasseName.", and how can we do it, please?

Can we declare global variables in ATL and QVT-Relations, if yes, how can we do it, please?

Thanks à lot,

With regards,
Bler.

Hi

No/Yes.

In QVTr I would recommend defining a GlobalVariable meta-model and then
passing an instance of this as an additional input to your transformation.

Hi

In principle, yes, but the Eclipse QVTd project is a long way from
meeting such things in practice.

Hi

A UML sequence diagram is just a form of model conforming to the UML
meta-model. Any respectable model transformation language should be able
to execute a transformation on it.
