Hi everyone,

I am working on the refactoring of UML models and therefore I use the ATL refining mode.

My question: is it possible to refine more than one element in an ATL rule (see example below)?

create OUT: UML refining IN: UML

rule Example {
      class1: UML!Class,
      class2: UML!Class ( = 'class1' and = 'class2'

      class1Refined: UML!Class (
         name <- 'Refined:' +
      class2Refined: UML!Class (
         name <- 'I don't wanna be newly created but also refined'

As you can see, I am matching two classes by name.

In the 'to'-block, only the first element (in this case 'class1Refined') refines the first element given in the 'from'-block (so 'class1').
In contrast, 'class2Refined' is newly created by ATL in the UML model.

Is there any possibility to also refine the matched element 'class2'?

Unluckily, documentation on the refining mode of ATL is not very detailed.

Any answer will be appreciated and if there are any unclarities, please ask Smile

Best regards,
