[news.eclipse.modeling.m2m] Re: [ATL] How to put model elements in a pac

Hi all,

I already found out how to do this using lazy rules.

Now I have one matched rule and two lazy rules.
Comments on how to do this in a better way are welcome of course.
This is my solution:

rule struct {
   from
           b : BoxMM!Box
   to
           m : UML!Model (
               name<- b.name
           ),
           ps : UML!Package (
               name<-'squares',
               namespace<-m,
               ownedElement<-BoxMM!Square.allInstances()->collect(e|squares(e))
           ),
           pc : UML!Package (
               name <-'circles',
               namespace <-m,
               ownedElement<-BoxMM!Circle.allInstances()->collect(e|circles(e))
           )
}

lazy rule squares {
    from
        s : BoxMM!Square
    to
        c : UML!Class (
            name<-s.name
        )
}

lazy rule circles {
    from
        s : BoxMM!Circle
    to
        c : UML!Class (
            name<-s.name
        )
}
