[news.eclipse.modeling.tmf] Re: How to assign attributes inside rules?

[Sebastian Zarnekow <Sebastian.Zarnekow@xxxxxxxxx>]

Hi Michael,

you may try to use a value converter to assign something to your int 
attribute. For example you may configure data type rules:

FooIntAttr1 returns ecore::EInt: 'x';
FooIntAttr2 returns ecore::EInt: 'y';

and use

Foo: alternative=FooIntAttr1 Alternative1 | alternative=FooIntAttr2 
Alternative2;

That should do the trick.

Regards,
Sebastian
