[RM-9304] [python API] isolate internal classes and methods

Created on 2024-11-14 13:27:11 by Didier Vibert. % Done: 0

In the pylibamazed python library only a fraction of the classes or of their methods are supposed to be public: that is to be used in a client code.

It would be beneficial to isolate the internal ones from the public ones to be imported by the client. One avantage is also to allow a systematic decoration by the @exception_decorator@ of the public functions.

One possible way to do it is to rename all the current classes with a dedicated suffix (eg @_internal@ or @_impl@,...) and inherit them from base classes with a non suffixed public name listing only the public method in the public base class.
