Hello,
Is it possible to obtain from an operation the class where it is defined? I need to call a template like this [template public genRefMethod(c : Class)] from the reference of an operation. I found that getNamespace().name return me the name of the class but I need the reference of the class and not the string of the name.

Thank you in advance.

Hi

Acceleo is an implementation of MOFM2T which is a modeling language. You should therefore use model references such as "namespace" and "name". "getNamespace()" is a bonus exploiting the underlying EMF implementation. Arguably it should not be available at all.

Assuming you are using the UML metamodel for which Fig 9.13 of the UML 2.5 spec shows that an Operation may be contained by an "interface", "datatype" or "class", so if you want the Class just use "class". Since Operation is an Element you can also use "owner". If "class" is a reserved word you will need to escape it as an underscore-prefixed single-quoted string "_'class'" (or more readaly, the deprecated underscore prefixed "_class"). The problems with reserved words infect the EMF implementation where the de-conflicted operation is "getClass_()".
