Re: [m2m-dev] FW: Quality Assessment of QVTO Model Transformations
|
Hi Phu,
I've posted sample _javascript_ that shows how to
save/load compiled qvto transformation (QVTo AST) with full information obtained
from .qvto file (even token positions as well).
Regards,
Sergey
Hello Ed Willink,
Thank you. Now I know that it is not easy to
obtain a QVTo AST with full composition. You are
right about my problem. The serialized AST I got seems to be the wrong
one. Please find the QVTo file and the corresponding xmi
file in the attachments
Is
there any suggestion about obtaining a QVTo AST with full
composition?
Best regards,
Phu

Hi Phu
If you have a true QVTo
AST then it should compose/share all the information you require.
When
you invoke Resource.save to serialize, what is the URI in the
XMI?
QVT 1.0 enabled at least three different interpreations of some
AST definitions and in some cases all three were wrong with the result that
not all child objects were composed and so those elements were omitted from
a serialized AST. Perhaps your problem is that you do not have a QVTo AST
with full composition.
Please post the XMI file resulting from
Resource.save.

Hello,
First I would like to thank for
suggestions from Ed
Willink and Sergey.
I tried several ways and I have found
out that it is possible to obtain AST of corresponding QVTo file by using
the InternalTransformationExecutor:
InternalTransformationExecutor
executor = new
InternalTransformationExecutor(transformationURI);
CompiledUnit
myCompiled = executor.getUnit();
OperationalTransformation
trans = executor.getTransformation();
Resource
res = trans.eResource();
EObject
qvtoModule = res.getContents().get(0);
Via the OperationalTransformation
object, generated AST can be
accessed and it certainly conforms to the metamodels QVTOperational.ecore and ImperativeOCL.ecore
For now it is possible to extract
some information from the AST, i.e. names of modeltype, transformation,
name of mapping operations. However I have not found out the way to access
other parts, i.e. bodies of mapping operation. Are there any
suggestions?
Last but not least, it would be much
better to access the AST if there is a way to serialize it. The ATL tool
kit allows obtaining the file of ATL model (generated AST) quite
easily. I was wondering if QVTO tool kit has a similar
function?
If you have any suggestions, please
let me know. Thank you very much!
Best regards,
Phu

[m2m-dev] Quality Assessment of QVTO Model
Transformations
Hi Phu,
QVTo
engine is able to be launched outside Eclipse.
Inside Eclipse you can obtain AST
of corresponding .qvto by means of EMF Resource, i.e. some like
follows:
URI uri =
URI.createURI("file:/.../my.qvto");
Resource res = new
ResourceSetImpl().createResource(uri);
EObject qvtoModule =
res.getContents().get(0);
Generated AST is conformed to
org.eclipse.m2m.qvt.oml/model/QVTOperational.ecore (for QVTOperational
package) and
org.eclipse.m2m.qvt.oml.ecore.imperativeocl/ImperativeOCL.ecore (for
ImperativeOCL package). In fact that models have some (very minor)
deviations from official OMG QVTO metamodels.
Regards,
Sergey
