[gme-users] how to compare enumeration values in ocl

[Sumant Tambe]

Hi folks,

What is the way of comparing an attribute that is an enumeration against 
    an enumeration constant in OCL? For example,

I have a model called Car, which has an enumeration attribute "Color" 
with 3 possible values: Green, Red, and Black. How do I write an OCL 
constraint that makes sure that all the cars are of Red color.

I tried

self.Color = ocl::Enumeration(Red)

but it does not work.

Any suggestions from OCL gurus out there?

Thanks,

Sumant.
