I would like to know if it is possible to access to ecore Elements of a Metamodel inside ATL code reflexively.

suppose I have a metamodel MM1, inside the metamodel I have a Class A, I would like to know how can I access to features of this class inside the code. More concretely suppose I have a helper:

helper def : getRef(a : OclAny) : Collection(OclAny) =
     ....

I would like to pass a Class to this helper and get back the list of all its references; i.e., I call

thisModule.getRef(MM1!A)

and this returns a collection of A's features; for example, if A has two references called called b1 and c1. I expect the above code to return {b1,c1}

Thanks

I found a solution to the question:

What I need to do is to complete the above helper code as bellow:

helper def : getRef(a : OclAny) : Collection(OclAny) =
        a->getEReferences();

The function getEReferences() does all the job for me! so simple!

if you would like to see all the accessible functions look at the methods for the EClass interface in the link bellow (or search "EClass interface javadoc"):

http://download.eclipse.org/modeling/emf/emf/javadoc/2.4.3/org/eclipse/emf/ecore/EClass.html#getEReferences()

Calling thisModule.getRef(MM1!A) would return a collection that contains all the references inside the MM1!A class!

Thanks
