Flattening a UML model with "refining" [message #97167]

Hi i wanted to flatten the package structure of a UML model,
does anybody know the best solution to do that?
i read a little bit about the "refining" execution mode, but it seems that
with a refinement i still have to write all the rules that copy a UML
model.
I also will have to deal with a huge amount of references that will
change, is there a solution that ATL provides for that?

Thanks.

Hi skander

i don't really remember how works the refines mode but i think you can
use a UML2Copy transformation (download :
http://ssel.vub.ac.be/viewvc/*checkout*/UML2CaseStudies/uml2 cs-transformations/UML2Copy.atl
; generated with :
http://ssel.vub.ac.be/viewvc/*checkout*/UML2CaseStudies/uml2 cs-transformations/EModelCopyGenerator.atl)

if you want to flatten you drop the rules for packages (Package2Package)

and in model rule (Model2Model)

you can change the rule into :

-- s is the source model

packagedElements <- s.packagedElements->union(
UML!Element.allInstances()->select(e | e.owner.oclIsTypeOf(UML!Package)
and e.owner <> s)
)

with this kind of rule ATL will copy each elements
except packages
and will be stored in packagedElement in top level model

do you want this kind of behaviour ?

thanks a lot for this very clear and quick help, i found another solution
by using UML2!Package.allInstances() in my original transformation, which
forgets about the hierarchy of packages, i found this very powerful in
ATL, but i will also try your solution.
Thanks a lot
