Hi All,
I have a simple problem. I have an Ecore metamodel with Upper Bound
multiplicity of an EReference as -2 (lower bound is 0). With this, i try
to map the ATL rules, But its not working.
But if I change the Upper Bound to -1 then it works!!! what to do? Is it
implemented in ATL or not? Is there any other way to do so?
Here is the code:
rule root {
from u : UML2!Model
to v : myML!DocumentRoot (component<-u.getCmpt(u)
}
rule component {
from u : UML2!Component
to v : myML!ComponentType(vendor<-'sophia.inria.fr',
library<-'myModel',
name<-u.name,
version<-'1.0')
}
waiting for the reply n thanks in advance,
-aamir-

Aamir,
Note that this corresponds to ETypedElement's
/**
* A value indicating that there is an unspecified {@link
#getUpperBound upper bound}.
* @see #getUpperBound()
*/
int UNSPECIFIED_MULTIPLICITY = -2;
Also note that isMany is computed by FeatureMapUtil.isMany because the
multiplicity depends on the multiplicity of the target feature.

As far as I have experimented, the multiplicity value of -2 causes a
strange effect in ATL that we can only create one instance/object for
that relation and this object can be user
created(myML!instancename...etc) or it can be a matching. but for more
than one it doesn't work.
so with this multiplicity value, we can have one instance for each type.
Lets see if someone opposes my observations...
thankx,
