Hi!
I’m trying to transform a model with a chain of aggregations to another
with an inheritance chain:
class a ------- transformation to ------> class A
owns 0..1 instanceOfb owns 0..* instanceOfB
class b class B (abstract)
inherits
owns 0..* instanceOfd class C (abstract)
inherits
class d ------- transformation to ------> class D

For the transformation only the first and last classes of the chain are
interesting. I’d tryed:

rule one {
from i: model1!a
to o: model2!A (
attribute <- i.attribute,

instanceOfB.D <- i.instanceOfb.instanceOfd
-- syntax error: mismatched input ‚.‘ expected LARROW

instanceOfB <- (i. instanceOfb. instanceOfd).oclAsType(model2!D)
--ClassCastException
)
}

Which is the right way write the rule?

Thank you in advance.

Hi,

Could you please remember to prefix the subject of your ATL-related
posts with [ATL]? See: http://wiki.eclipse.org/M2M

It seems that you miss a comma on the line with the syntax error.

Regards,

Frédéric Jouault
