Hello,
I am super new to EOL, so here I have a really dummy question.

here is the example.
http://www.eclipse.org/epsilon/examples/index.php?example=org.eclipse.epsilon.examples.modelmodification

in line 9 we use

Model.store(Model.modelFile + 'copy.model');

I did read the epsilon book, but I did not understand how can I know there is a "Model" class in EOL, and what is the other methods? where can I find it?

Thanks advance for any information!

Hi Tong,

"Model" is the name of the model in the Run configuration of AddLeaves.eol.

Hi Dimitris,

Thanks for helping!
and I have another question.
I am facing a problem that in model to model transformation, the meta-model may also be modified time to time. I don't want to rewrite .etl files every time. Is that possible to do model transformation with configuration? maybe is transformation rules itself also conforms to a metamodel?

Thanks a lot!!

Tong

Hi Tong,

An ETL transformation can access more than two models, so it should be perfectly feasible to add a third "configuration" model.

Cheers,
Dimitris
