hello everybody,
I would like to know if it is possible to have a variable number of output
models. For example, it is possible to have one output model for each class
mod?:
IN:
<mod id=1>
....
</mod>
<mod id=2>
....
</mod>
<mod id=3>
....
</mod>
OUT1:
<mod id=1>
....
</mod>
OUT2:
<mod id=2>
....
</mod>
OUT3:
<mod id=3>
....
</mod>
Thank you
Franco

The current version of ATL doesn't allow doing this: you have to
explicitly define in the ATL file header the input and output models (as
well as their respective metamodels).
A solution may be to use what is called a HOT (high-order
transformation), i.e. a transformation that generates another
transformation. This way you can dynamically determine the number of
input/output models into the generated transformation.
Here are two use cases using HOTs:

I hope this may help you.
Best regards,
Hugo
