[news.eclipse.modeling.m2m] Re: [QVTo] Compiled transformation?

[Alex <alex.leites@xxxxxxxxx>]

For what it is worth - and I know, not much - I would love to see this implemented. Performance, especially on larger models, would be the primary driver for me. While the QVTO interpreter does a pretty amazing job, I would expect a native Java transform to be significantly (orders of magnitude?) faster still. Direct (strongly typed) rather than reflective access to EMF models is likely to play a role as well ...

Wouldn't it be nice to implement this as QVT transform from QVT model to Java model - and compile that transform later, of course ...  :p

This also remins me of "Octopus" by Jos Warmer and Anneke Kleppe - it had native Java codegen from OCL 2.0 several years ago ... Back then it used custom OCL model and runtime stdlib, custom data metamodel (with textual DSL and import from UML XMI), custom simplified Java models, "transformation" in code, etc. - and worked great.
