RE: [uml2-dev] UML2 profile: Redefine inherited operation
|
Theresa,
Please use the newsgroup (eclipse.modeling.mdt.uml2) for questions like this in the future.
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.

Subject: [uml2-dev] UML2 profile: Redefine inherited operation
Hello,
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?
Regards, Theresa
