[MOFScript] eAnnotations-question [message #378057]

Hi everybody,

i am trying to access the following eAnnotations - entry of a UML2 Model
using MOFScript.

<transition xmi:id="_HBYoxP5OEdut2qo8JgL_7Q" name="OVERVIEW"
target="_HBO3i_5OEdut2qo8JgL_7Q" source="_HBO3gv5OEdut2qo8JgL_7Q">
<eAnnotations xmi:id="_HBYoxf5OEdut2qo8JgL_7Q" source="abstract">
<details xmi:id="_HBYoxv5OEdut2qo8JgL_7Q" key="type"
value="Transition"/>
<details xmi:id="_HBYox_5OEdut2qo8JgL_7Q" key="stereotype"
value="State Transition"/>
<details xmi:id="_HBYoyP5OEdut2qo8JgL_7Q" key="bendpoints"
value="1"/>
</eAnnotations>
</transition>

I tried the following transformation:

texttransformation ExampleTransformation (in
uml:"http://www.eclipse.org/uml2/2.0.0/UML") {
uml.Transition::main () {
self.eAnnotations->forEach(annot:uml.EAnnotation){
//do something
}
}
}

This results in the following error message:

Error: MTTParseError: Type not found: 'EAnnotation' in metamodel 'uml',
line: 0, column: 0

Is there any way in MOFScript to access the eAnnotations content?
Any help is appreciated.

Greetings,
Christian

Hello Christian,

I think the problem is that you are using EAnnotation from uml.
You should try the following,

texttransformation ExampleTransformation (in
uml:"http://www.eclipse.org/uml2/2.0.0/UML") {
uml.Transition::main () {
self.eAnnotations->forEach(annot: ecore.EAnnotation){
//do something
}
}
}

The ecore metamodel is available through the prefix ecore.

G

Christian,

We found similar obstacle.
We believe this happens, because the .ecore metamodel
is not taken into consideration by MOFscript,
when just indicating as input a .uml model..

Therfore, MOFscript does not consider that the UML elements,
are also ecore elements, and therefore have eAnnotations.

By explicitely including the ecore metamodel as an input parameter,
MOFscript will "find" the eAnnotations.

The hassle is that when you run the transformation,
MOFscript launcher will ask you for an input model
(to serve as the ec: parameter),
but you can simply provide the every same .uml input model,
it doesn
