[Acceleo] Any plans for MTL->Java codegen? [message #1264679]

Good day m2t,

Are there any plans to implement a Java code generator for MTL templates?

I'm envisaging something akin to the way JET builder generates Java code
from JET templates, for ultra-fast transformation of user domain models.
It strikes me that the maturing OCL->Java code generator would be a good
base (although I assume the OCL converter must actually use JET to
generate its Java code).

Thanks,

Hi

The OCL->Java generator started out using Acceleo templates, but it
rapidly became clear that the problem was really a cascade of MtoMs
followed by an MtoT. Doing MtoMs using MtoT queries is not a clever
approach. The text generation was also simple compared to its queries so
the OCL to Java is currently pure Java code. Once we have the main OCL
mappings defined as and autogenerated from transformations, we might
reimplement the code generator using transformations too; don't hold
your breath.

But in principle extending the OCL to Java generator is sensible.

It is already extended for the QVTi code generator; ? the only
transformation language that compiles to Java ?

Regards

Hi Ed,

Thanks for the quick response.

I hadn't actually looked at your OCL -> Java code so it was just a naive
guess that it might be JET, as with EMF. I'll have a closer look...

Rgds,
