Hello,

I have a pattern which is based on UML diagrams annatated with a profile. I seek to automatically instanciate it for futur transformation. Is it possible to do that using EMF concepts ?

Thanks for help,

Hi,

What is a "pattern"? And what does it mean to "instanciate" one?

Almost anything can be done with EMF, but we'll need more information
about your use case in order to be helpful.

Cheers,

Christian

Hi,
A pattern is a generic model that defines a solution for a specific problem. It may be modeled using graphical or textual modeling languages. In my case I defined a pattern modeled through UML and annotated using MARTE profile.
Instanciate a pattern means its application on a specific system (The same pattern may be applied on different systems having the same problem, the instanciation depends on systems caracteristics).
I want to realize an automatic instanciation using EMF concepts.
Is this possible?
Thanks for your reply,

Hi Amina,

You can either use an in-place model-to-model transformation (e.g. using QVTo or ATL), or a model-to-text transformation (e.g. using Xtend or Acceleo).

The first option acts as a "refactoring" (you modify your model by applying a pattern). The second one acts as a "compiler" (you apply the pattern when producing a specific artifact, and the model remains unchanged).

All these tools are not provided directly by EMF, but are built on top of it, and can handle any EMF-based model (including Eclipse UML models, built with or without Papyrus).

Regards,
Camille

Hi Camille,

You mean that i can instanciate my pattern without making MARTE2Ecore mapping ?
If possible, would you like to give me a tutorial about this. I am a new user of MDE concepts Smile

Thanks for your reply,
Best regards,
