Genmodel and interface default methods [message #1797593]

I can't see any direct way to define an interface in my model and to implement default methods in the interface and indicating that the implementing classes don't have to provide any implementation either in the genmodel or via some form of javadoc annotations like @Implements.

Am I just missing a recent feature? I don't really feel like providing a generated not for each with a super call to the default (SONAR will now complain :) )

With Java continuing to improve the role of interfaces, some related features would be very welcomed.

No, EMF has no support for default interface methods, and in general has no specialized Java support beyond Java 1.5.

Perhaps someone cares enough to fund the effort for such a new feature.

Ed,

Thanks for the quick reply as always. Given our transition away from RCP and move to a full DS mode, we are planning a number of tweaks to the generator early 2019, and we'll look into including this into the fold. Might solicit your feedback to adopt a solution that can be shared.

Cheers,
Alain

Hi

I've just been evolving an EMF model under API tooling and had a play to see to what extent default might help.

EMF enhancement https://bugs.eclipse.org/bugs/show_bug.cgi?id=541284 raised to place the discussion somewhere more pertinent.
