I have an ecore model where a lot of classes have 3 attributes for audit information. I want to replace these 3 attributes with a reference to a class that contains all those attributes. That class is contained in another ecore model.
Therefore I wrote the following transformation:
-- @atlcompiler atl2010
-- @nsURI ECore=http://www.eclipse.org/emf/2002/Ecore
module refactorAuditInfo;
create output: ECore refining input: ECore, additional: ECore;
rule addReferenceToAudit {
from
input : ECore!EClass (
input.eStructuralFeatures -> exists(e | e.isAuditInfoFeature())
)
to
auditInfoReference : ECore!EReference (
eContainingClass <- input,
eType <- input.refImmediateComposite().auditClassifier(),
name <- 'audit',
eReferenceType <- input.refImmediateComposite().auditClassifier().debug()
),
outputClass : ECore!EClass (
eStructuralFeatures <- input.eStructuralFeatures.append(auditInfoReference.debug())
)
}
helper context ECore!EPackage def : auditClassifier() : OclAny =
thisModule.additionalDbadm.eClassifiers -> select(e | e.name = 'Audit').first();
helper def : additionalDbadm : ECore!EPackage =
ECore!EPackage.allInstances()->select(e | e.nsURI = 'http://additional.dbadm/1.0').first();
helper context ECore!EStructuralFeature def : isAuditInfoFeature() : Boolean =
Sequence{'beDat', 'beUser', 'beRolle'}.contains(self.name);
However I get a NoSuchElementException when I execute that transformation. The output is:
additional!Audit
refiningTrace!<unnamed>

The NoSuchElementException is raised during execution of the line
eStructuralFeatures <- input.eStructuralFeatures.append(auditInfoReference.debug())
Note that the line information of the ATL stack is not matching the correct line in the above ATL transformation, because I left out some other stuff.
I'm using Juno with ATL 3.3.1. Does anyone know, why this exception is raised and what I'm doing wrong? Thanks

I found the solution for the NoSuchElementException. When i change the VM the transformation is running in to the regular VM, then I get the error message
org.eclipse.m2m.atl.engine.vm.VMException: Could not find operation contains on Sequence(OclAny) having supertypes: [Collection(OclAny)]
at MECore!EStructuralFeature;.isAuditInfoFeature() : ??#11(refactorAuditInfo.atl[37:2-37:60])
local variables = {self=input!betId}
local stack = []
So the line
Sequence{'beDat', 'beUser', 'beRolle'}.contains(self.name);
must be rewritten to
Sequence{'beDat', 'beUser', 'beRolle'}->includes(self.name);
Thanks for your help Sylvain.
