Hi,
Can anyone tell me is it possible to reference or use some existing
models (based on the dest metamodel, but not generated in the ATL rule)
during the transformation?
For example, MMa is the source metamodel, MMb is dest metamodel, Ma is
source model, Mb is the target model. And there are Mb1,Mb2,Mb3 which
are models following the MMb metamodel, and they are some libraries
which Mb maybe use.
Is it possible to use the Mb1, Mb2,Mb3 model libs during the transformation?

Hi Yue,
You can use several model as source in your transformation.
With your example it gives in the header of your transformation
something like :
module MMAext2MMB;
create OUT : MMB from IN1 : MMA, INMb1 : MMB, INMb2 : MMB, INMb3 : MMB;
Hope it helps.
Best regards,
Guillaume

Hi Guillaume ,
Thanks for your help.
In this solution, can the models be used as a library?
Actually I'm looking for a way to use the models which is a libray of
the dest metamodel.
regards
Yue

Hi Yue,
I'm not sure I understand your question, but I know that you can get the
information contained in all the source models to use it for the
construction of your dest model. So, it must be sufficient to do what
you want.
Best regards.

Hi Guillaume,
Thank you so much.
By the way, do you have such an example? or where can I find one?
best regards
Yue

Hi again,
I only example I have for you is on the ATL Howtos, at
http://wiki.eclipse.org/ATL_Howtos#Using_an_XML_file
This example show how to use an XML file to set parameters in a
transformation.
This type of actions can be used with every type of models where you
need to get informations.
This informations are retrieved by using helpers (in the sample the
helper is called getParameter to retrieve value from the XML model. Of
course, if your model are not XML model, you do not need the specific
XMLHelpers ATL library).
Best regards.
Guillaume

Hi,
one problem of this approach is that you can only have a fixed number of
libraries, right? Is there a way to pass an arbitrary number of
libraries (which are chosen at runtime) to an ATL transformation?

Stefan

That's it, it is impossible yet to have an variable number of in models
in an ATL transformation. You must know the exact number of in models
during the specification of the transformation.
