[EMFTVM] What is the essence of .emftvm file? [message #1597793]

Hi,

I intend to write an ATL transformation to transform my model transformation language into EMFTVM (trying to mimic the way that simpleGT or ATL did it).

My question is that my output should be a .xmi file right? But when I open the .emftvm file that ATL/SimpleGT generated using text editor, it seems being post-processed (i.e. not a .xmi file).

May I ask what I am missing?

In addition, does that mean if I generate .xmi file, it will not be able to interact with EMFTVM's API, e.g. DefaultModuleResolver?

Best,
Zheng

EMFTVM uses a binary bytecode format described here: http://git.eclipse.org/c/mmt/org.eclipse.atl.git/plain/plugins/org.eclipse.m2m.atl.emftvm/doc/EMFTVM.html
Loading/saving is implemented in EMFTVMResourceImpl, which is automatically used by EMF when the .emftvm file extension is used. You can indeed generate XMI as well, but the DefaultModuleResolver will only load binary .emftvm files.

Cheers,
Dennis
