Problems redefining an inherited operation [message #478225] Sun, 08 March 2009 17:34 Go to next message

I have problems redefining an inherited operation.

I'm working on an UML2 profile for my project in MDSD.

Stereotype MediaComponent is an abstract classifier. The subclass
stereotype MediaContainer is associated via generalization. Both are
extensions of (ecore) EClass. I redefine an operation addMedia(Media) in
stereotype MediaContainer which is inherited from from stereotype
MediaComponent by setting the property "Redefined Operation" to point to
the general operation. Method name and parameters are set to the same
values as in the general operation, only the included code shall be
redefined in the generated code.
When I try to define the profile I get to one error and one warning for
each operation I try to redefine.

The error is:
Operation addMedia is a duplicate of inherited operation addMedia()

The warning is:
Operation addMedia sould be annotated as redefinition of operation
addMedia()

When I remove the operation from the subclass everything works fine. When
I remove the property "Redefined Operation" I only get the error
concerning the duplicate operation.

I tried various ways to solve the problem but didn't find any solutions.

Any ideas?

Theresa,

The only way to support redefinition (and other UML-specific constructs like
subsetting and unions) in a profile is to define the profile statically.
Dynamic profile definitions make use of the default Ecore mapping, and Ecore
does not support redefinition. With static definitions, you generate code
for the profile just as with any other metamodel, and have complete control
over the generator settings and implementation.

Thanks for you help Kenn.
I changed my profile using the following little tutorial
( http://dev.eclipse.org/newslists/news.eclipse.modeling.mdt.u ml2/msg00817.html).
It worked fine so far, but when I try to create the EMF model and load my
Profile I still get an error (or more a warning) for each operation I
tried to redefine (Operation x should be annotated as redefinition of y)
and additionaly several warnings for uml redefinitions. I can proceed
because I selected "process all" and the genmodel is created but not the
redefinied operations which are all missing.
What could be the problem?

Theresa,

You need to select the option to process redefinitions (in the EMF
project/model wizard) rather than reporting them...
