Wrapper interface

[ElGigi]

Added a Wrapper interface to identify enclosing models.

And thus allow for example to test if a included model implements a particular interface like LoggerAwareInterface.

Cool! Thanks @ElGigi, I think we had something like this before but I can't remember why we got rid of it! I'll give it a closer look when I can.

Ok I left some comments ... I remember having an interface like this before, but I can't remember why we removed it exactly. My guess is that it didn't serve any internal use cases so we just dropped it.

I can think of a few external use cases for an interface like this. The one you mentioned is a good one. Do you have any in particular in your own projects?

P.S. To fix the coding style automatically you can run compose fix from the project root

In our project, we abstract of the final model. To allow to define own model in sub-libraries.

The final service don't known the model but only interface, so to define if we set a logger or if the model is trainable, we need to retrieve the base estimator.

I do 👍

I didn't want to do that because it would modify too many files. Unrelated to my PR.
