Hello,
I am currently working on my graduation project, which is to research the performance of model transformation languages. For this, I am performing transformations in three different languages (ATL, QVT-R and QVTo), altering size and complexity meta-models, models and transformations.
However, I ran into a small problem I hope you can help me with. For ATL and QVT-R (I use mediniQVT for the latter), there is the possiblity to print the time taken for the transformation te execute. I would also like to do this for QVTo, but have not found a way to do this: the tool does not allow for this functionality, and I have yet to find a way to do this in pure QVT.
Would anyone know how I can time the execution of QVTo transformations?

Hi
QVTo support black box transformations so you can implement your own
timing in a Java BB Tx.

Hi,
Thank you very much for your reply. I have looked in to QVTo blackbox operations, and, at the risk of sounding like an idiot here, I have not managed to get even the example running.
How should a library be configured an run in order to be available to the QVTo transformation? I have loaded the "Black-box Library Definition" example, but have not managed to use any of the library functions in the transformation: should it be run as a plug-in (right clicking the MANIFEST.MF and run as an Eclipse application), using said plug-in as a dependency in the QVTo project and running that as a plug-in, I think I have tried about everything. Can anybody give me a clear tutorial on this or explain how to do it? The Eclipse wiki is not that clear on this.
Regards,
Steven Bosems
