Adding custom methods in Python

[Michael Armida]

Regarding the Python integration, is there a way to extend the behavior of the classes generated from a schema file? For example, a way to extend those classes to add methods in a child class, or to add a mix-in class?

A proper solution would ensure that custom behaviors are associated with objects loaded from a message, and conversely, would not interfere with the serialization of an object to a message.

The classes generated from the schema are nothing more than offsets into a buffer, meant to make it easy to access the data.

You could subclass them, but since they're returned from generated code, that wouldn't do you much good. If you want to add functionality to them, the only way would be by wrapping them, or use plain functions.

Is there any way to add to the generated code reliably and consistently? Or to get the generated code to include a class as a mixin?

[Wouter van Oortmerssen]

There's no explicit functionality to add to the generated code, no, beyond what Python already allows.
