Thanks for the correction. You can wrap RNA instances in your own classes and pass them around.
eg: >>> class MyDecorObject(bpy.types.Object): ... @property ... def my_prop(self): ... return "Foo" ... >>> o = MyDecorObject(bpy.context.object) >>> o.my_prop 'Foo' But this isn't done anywhere in Blender AFAIK On Mon, Mar 12, 2018 at 10:31 PM, Toni Alatalo <[email protected]> wrote: > Python decorators do not implement the Decorator Pattern, they are > different things.
