[ATL] Load ressources in UML model [message #528090]

Hi all,

I am coding in ATL a model transformation to a UML model. In my targeted .uml model I got a UML class with some properties inside. I would like to type these properties with other UML class that I defined in another .uml file. How can I do that in ATL???

When creating a .uml model, I can load another .uml file with a "load resources" function and then apply the new loaded types in my .uml models... Is there a similar function or a way to do that in ATL?

Thank you for your help!
Damien

Just add the other model as input in your transformation and activate the "allow inter model references" option.

Then you can do things like :

type <- UML2!Class.allInstancesFrom('MyOtherModel')->select(e | e.name = 'MyType')->first()

Thank you Sylvain!

Your solution seems great Sylvain, but unfortunately I didn't succeed to use it...

I adapted this code to my problem:
type <- UML2!Class.allInstancesFrom('MyOtherModel')->select(e | e.name = 'MyType')->first()
and when launching the transformation there is no mistake, but the types of my properties are still empty...

How can print in the console the value of "UML2!Class.allInstancesFrom('MyOtherModel')->select(e | e.name = 'MyType')->first()" in order to investigate what happens?

Regards,
Damien

UML2!Class.allInstancesFrom('MyOtherModel')->select(e | e.name = 'MyType')->first().debug('debug')

debug is a function that takes self as input and returns self while printing self to the console.

Have you activated the allow inter model references option ? This option allows a model to reference others (MyOtherModel here). If it's off then it won't work.
