Hello ,

I want to transform a collection to another type of collection in a atl
file. I'm new to atl scripts and I don't know where to put exactly the
code who will transform entites to datalayer.

Thanks.

transform.atl:

module transform; -- Module Template
create OUT : detailed from IN : itarone;
rule Domaine {
from
a : itarone!Domaine
to
b : detailed!Domaine (
name <- a.name
)
}

My source ecore is represented by the following mk3 content :
package source{

class Domaine {
attribute name[0-1] : ;
reference entites[0-1000] ordered container : Entite;
reference usecases[0-1000] ordered container : UseCase;
reference subDomaines[0-100] ordered container : Domaine;
}

class Entite {
attribute name[0-1] : ;
reference usecases[0-1000] ordered container : UseCase;
}

class UseCase {
attribute name[0-1] : ;
reference entites[0-1000] ordered : Entite;
}
}
My destination ecore :
package destination{

class Domaine {
attribute name[0-1] : ;
reference dataLayer[0-n] container : DataLayer;
}

class DataLayer {
attribute name[0-1] : ;
}
}

Hello,

Could you please remember to prefix the subject of your ATL-related
posts with [ATL]? (see http://wiki.eclipse.org/M2M)

You should do this in another rule:

rule Entite2DataLayer {
from
s : itarone!Entite
to
t : detailed!DataLayer (
name <- s.name
)
}

Then, you can add:
dataLayer <- a.entites
in your Domaine rule below:
name <- a.name
