| define getter of derived volatile attribute [message #1060723] |

Hi,
I have defined a derived volatile attribute. Now I need to implement the
getter. By default, the EMF generator creates a method stub, and I have
to manually implement the body. In order to avoid trouble in case of
re-generation (actually, I'm using an Xtext post processor to add the
derived attribute, so "@generate not" is not working), I would like to
define the body of the getter in the model, similar to the body of an
operation (which can to be defined in an annotation). Is that possible?
Actually, I would like to simply add the body in the post processing
step, when I define the attribute.
Regards,
Jens

Jens,
The generator has methods like this
protected String getGetterBody()
{
EStructuralFeature eStructuralFeature = getEcoreFeature();
EAnnotation eAnnotation =
eStructuralFeature.getEAnnotation(GenModelPackage.eNS_URI);
return eAnnotation == null ? null :
(String)eAnnotation.getDetails().get("get");
}
that will extract the stub into the generated code.
