Create a called rule which gives you a set of operations (your 2
accessors) for a property and add this set to the classe operations set.
Be care that in ATL the Union method on sets return a copy of the set so
you must reaffect the result to the class:
ownedOperation <- ownedOperation->union(yourCalledRule(xxx))

Hello,
Thank you for the answers.
Vincent, I have try your solution, but i have a error.
It doesn't find a operation.
Have you got a idea for the solution ?
Thank.
see the error message bellow :
Operation not found: OUT!property1:UML2!Operation.not()
at __applydao(persistence.atl[14:21-14:75])
local variables: self=thisModule, link=org.eclipse.m2m.atl.engine.emfvm.lib.TransientLink@166aa35, a=IN!Departement:UML2!Class, d=OUT!DepartementDaoImpl:UML2!Class, sf=IN!property1:UML2!Property
at __exec__(persistence.atl)
local variables: self=thisModule, e=org.eclipse.m2m.atl.engine.emfvm.lib.TransientLink@166aa35
at main(persistence.atl)
local variables: self=thisModule
see the code of my transformer :
module persistence;
create OUT : UML2 from IN : UML2;
helper context String def : firstUpper() : String =
self.substring(1, 1).toUpper()+self.substring(2,self.size());
rule dao {
from a:UML2!Class
to d:UML2!Class (
name <- a.name +'DaoImpl',
ownedAttribute <- a.ownedAttribute->select(sf | sf.oclIsKindOf(UML2!Property)),
ownedOperation <- a.ownedOperation->union(a.ownedAttribute->select(sf | thisModule.accessor(sf)))
)
}
lazy rule accessor {
from a:UML2!Property
to o:UML2!Operation (name <- a.name)
}
Cordialement,
Guillaume Landriu
