[EOL] How are models resolved in eol? [message #841069]

Hello,

The "Create an OO model with EOL" has brought this question. In the eol file one can see:

var m : new Model;
m.name := 'm';

In the launch (or the ant) the model has a name "OO". How does eol match the OO model to the m variable so that at the end the OO.model file contains m:Model as created in the eol file?

Regards,

Horacio

Hi Horacio,

Model is an EClass in the OO metamodel. The EOL interpreter iterates through all the models it can access (in this case that is only the OO model) and calls their hasType("Model") method. The OO model returns "true" and then the interpreter calls its createInstance("Model") method which returns a new EObject conforming to the Model EClass. Does this perhaps answer your question?

Cheers,
Dimitris

Yep, thanks a lot Dimitris! I think you meant "metamodels" when u say that eol iterates through all the models it can access.

But now I wonder what happens if there are two or more metamodels with a "Model" EClass... I am guessing first find Wink

.
