Hi,

Can anyone tell me is it possible to reference elements of the output
model during an ATL transformation?

Hi Lisa,

Yes you can. Output elements are given a name. You can use it as a
reference to the create object (but only in the rule defining it).

Happy new year,
Quentin

Hi Quentin,

Thank you so much for your answer, the only problem is that I want to
reference an output element from a rule that doesnt create the object. Is
there any way of doing this that you know of?

Thank you and Happy New Year to you too,
Lisa

Hi Stefanie, you have to import the profile as metamodel if you want to
apply some stereotype to your output elements.

This is the header of a sample transformation from profile A to profile B:

module moduleName;
create OUT : UML2 from IN : UML2, PRO : UML2;

IN and OUT are the UML2 metamodel and PRO is the .uml definition of
profile B.

The following is a rule that matches a stereotyped UML Component and
generates a stereotyped UML Class:

rule comp2class{
from
s : UML2!Component
(
s.isStereotypeApplied('<stereotypeName>')
)
to
t : UML2!Class(
-- bindings
)
do {
t.applyStereotype(<here you put the Stereotype definition contained in
PRO>);
t.setValue(<Stereotype definition contained in PRO>, '<propertyName>',
<propertyValue>);
}
}

helper context UML2!Element def: isStereotypeApplied(name : String) :
Boolean =
not self.getAppliedStereotypes()->select(p |
p.name = name
).isEmpty();

This is how I tackled the problem of applying stereotypes to UML elements
and set the values of UML Tagged values.

I hope this will be useful, regards

Ivano

Hi Lisa,

OK! So, in ATL, you assign a reference of an output object with an input
object. This last will be replaced by a reference to the object created
from it.

Therefore, you do not handle directly the references but rather let them
to ATL.

I hope this meets your question.

Quentin
