[EPL] type-of vs. kind-of relationships [message #1076369]

Hi!

It seems for me that the roles in the patterns are checked by the type-of relationship.
Consider the pattern

pattern MyPattern
   obj  : SomeType,
   obj2 : A
      from : obj.elements

where I have the types "SomeType", "A" and "B", s.t. "B" is a subtype of "A".

If "obj.elements" is a collection of instances of type B then the pattern is not applied, because it seems to me that the type-of relationship is checked in the role. Is it possible to modify this to a kind-of relationship role checking without writing everything down in a "match" clause and checking manually to "isKindOf(...)"?

I also tried to write "Any" instead of "A" in the role, but I get an error, that "Any" is not a meta-class in my model.

Best regards,
Alex.

Hi Alex,

Thanks for reporting this. I've filed a bug report [1] and fixed this in the SVN. A new interim version should follow shortly.

Cheers,
Dimitris

Hi Dimitris!

There is an interim update for Kepler. Is there also an update for Juno available or will it appear later?

Best regards,
Alex.

Hi Alex,

The Kepler interim update site should also work for Juno. The only caveat is that if you need the "EMF Model Comparison for EUnit" feature you'll need to install the latest version of EMF Compare first as there have been breaking changes in this project between Juno and Kepler.

Cheers,
Dimitris
