Hi,
when I generate an ecore model based on an UML model, how can I then access the UML (class) model from an (instance)
EObject? I would like to do something like "myObject.eClass().getTheCorrespondingUMLClass()".
Somehow I can't find this explained anywhere.

Thanks for helping

Joel

Joel,

There's no mapping maintained to do that, and certain not in the form of
API whereby the Ecore model has direct references to the UML model. .
If you know which UML package corresponds to which EPackage (via the
nsURI presumably), then likely the name correspondence between the
EClass and the UML UML would be sufficient to do the mapping...

Hi Ed,
I was afraid that this information is not stored anywhere explicitly...
Of course the ecore API has no reference to UML, but I thought there would be generically accessible annotations or
something like that.

I'll think of something,
Thanks
