Hi,

I would like to know the possibility of overriding the ocl derivation statements of derived attribute in specialization class?

Is it supported in Ecore?

Cheers,

Hi

I'm not entirely clear what you mean.

Generally (UML, Java, Ecore), Properties are not overrideable, although
in UML they are redefinable.

If you want overriding you should use Operations, and if you want it to
look like a Property, introduce a Property at the root that delegates to
an Operation.
