Transform UML models with applied profile [message #1856702]

Hi,

I am trying transform UML models to which I have applied a profile to instances of ecore models.
For some mapping operations, I need some mapping conditions.

For example:

modeltype profile uses '...';
modeltype target uses '...';
modeltype uml uses 'http://www.eclipse.org/uml2/3.0.0/UML';
....
mapping uml :: PackageableElement :: PE2Element1) : target :: Element1
{
result.name := self.name;
}

Now, this mapping operation should take place only if the StereotypeElement1 stereotype has been applied to the PackageableElement.
How would I go about writing the condition to do that?

In the following, I also provide part of the uml model that will be transformed.

  
<uml:Package xmi:id="_mKmYkH1fEe2iL8nfRIbyXQ" name="HelloWorld">
  ...
<packagedElement xmi:type="uml:Class" xmi:id="_mKrREH1fEe2iL8nfRIbyXQ" name="Test">
     <eAnnotations xmi:id="_mLDrkH1fEe2iL8nfRIbyXQ" source="uml2.diagrams" references="_mLDrkX1fEe2iL8nfRIbyXQ">
       <contents xmi:type="umlnotation:UMLDiagram" xmi:id="_mLDrkX1fEe2iL8nfRIbyXQ" type="Structure" element="_mKrREH1fEe2iL8nfRIbyXQ" measurementUnit="Himetric">
         <children xmi:type="umlnotation:UMLShape" xmi:id="_mLDrkn1fEe2iL8nfRIbyXQ" type="StructureDiagramFrame" element="_mKrREH1fEe2iL8nfRIbyXQ" fontName=".AppleSystemUIFont" fontHeight="8" transparency="0" lineColor="14263149" lineWidth="1" showStereotype="Label">
           <children xmi:type="umlnotation:UMLShapeCompartment" xmi:id="_mLDrk31fEe2iL8nfRIbyXQ" type="StructureCompartment"/>
           <children xmi:type="notation:BasicDecorationNode" xmi:id="_mLDrlH1fEe2iL8nfRIbyXQ" type="Name"/>
           <layoutConstraint xmi:type="notation:Bounds" xmi:id="_mLDrlX1fEe2iL8nfRIbyXQ" x="1058" y="1058"/>
         </children>
       </contents>
     </eAnnotations>
     ......
</packagedElement>
....
</uml:Package>
<Default:DefaultLanguage xmi:id="_mKmYpn1fEe2iL8nfRIbyXQ" base_Package="_mKmYkH1fEe2iL8nfRIbyXQ" defaultLanguage="DL"/>
<Profile:StereotypeElement1' xmi:id="_mK56kH1fEe2iL8nfRIbyXQ" base_Class="_mKrREH1fEe2iL8nfRIbyXQ"/>

Hi

Unfortunately QVTo still uses the Classic OCL that, just like the OCL specification, lacks clear typesafe support for UML Stereotypes.

(The newer Pivot-based OCL extrapolates hints in the sole example of the UML2 specification to make usage much simpler.)

So you must fall back on the UML2 project Java API with operations such as getAppliedStereotypes and oclAsType casts,. You can find examples of e.g. getAppliedStereotype in

https://git.eclipse.org/r/plugins/gitiles/ocl/org.eclipse.ocl/+/refs/heads/master/examples/org.eclipse.ocl.examples.build/src/org/eclipse/ocl/examples/build/qvto/UML2EcoreSynthesizer.qvto
