Hello all,
I investigate the way to call in Java a QVTo transformation, not from the qvto file but from an XMI file representing the transformation (conforming the qvto metamodel).
Does anyone have a clue to do so ?
Thanks,
Tom
PS: For those interested in the reason why I do that, read below
I "transform qvto transformation", i.e I use qvto transfos to transform other qvto transfos. First, I create an XMI file "mytransfo.xmi" from a qvto file "mytransfo.qvto" using the following code and the Eclipse/Qvto launcher:
modeltype qvto uses qvtoperational::expressions('[...]eclipse.org/QVT/1.0.0/Operational');
transformation copyToXmi(in model : qvto,out outmodel : qvto);
main()
{
model.objects()[OperationalTransformation].deepclone();
}
"mytransfo.xmi" is an instance of the qvtoperational metamodel. Then I transform this instance to change names, mapping operations, parameters... and obtain a "finaltransfo.xmi". I finally want to execute this final transformation, directly from the XMI file without having to translate the model to some qvto code (m2t).

Hi
Nicolas Rouquette has a patch awaiting source approval. If you contact
him, nicolas.f.rouquette _at_ jpl.nasa.gov, he may able to let you have
a copy. Be aware that the XMI file is not OMG compliant and may evlv e
to be OMG complinat once OMG defines an XMI serialisation to comply with.
