Cannot access uml2 stereotype values in ATL [message #26466]

Hi,

I've written an ATL transformation converting a uml2 file (created by
eclipse uml2) to an output DSL model file.

The input has some profiles applied, and these are handled correctly by
the transformation except that I don't know how to access the stereotype
properties that have been applied to via the stereotype to my model
elements. For example the UML model has stereotype 'Car' applied a to UML
type Class, and I need to get the Car 'colour' property value as applied
to a Class.

Thanks for any help.

Hello Paul,

you can try with:
yourUMLClassType.getValue(yourUMLClassType.getAppliedStereot ype('Car'),
'colour')

You can use the method getValue (yourUMLClassType.getValue(yourStereotype,
propertyName)) to get the value of a stereotype property. The method
getAppliedStereotype(String StereotypeName), is used to get the stereotype
element applied to your UML element. RegardsBea

Thanks Bea.

I've tried your suggestion as follows but this gives a
NullPointerException at at
org.atl.engine.repositories.emf4atl.ASMEMFModelElement.invok e(ASMEMFModelElement.java:522).
My guess is that it can't resolve the value (from getValue(..)) in the EMF
model structure of the UML!Property element.

from
c : UML!Property (c.getAppliedStereotypes()->exists(s | s.name = 'Car'))

to
car: MyModel!Car(
name <- c.name,
colour <- c.getValue(c.getAppliedStereotype('Car'), 'colour')
)

Have you try with the qualified name of the applied stereotype?:
colour <- c.getValue(c.getAppliedStereotype('YourProfileName::Car'),
'colour')

Ok, I'll give that a go when I get a chance to look at this again.
Thanks

Hi Bea,

Just got round to looking at this again- Your suggestion to use the fully
qualified stereotype name made it work.

Thanks for your help
