How to handle classes as datatype in python-dbus

Question

I'm new to python and dbus, but is there a data binding (= a way to send and receive) python classes via dbus-python?

My class looks like this:

class Item:

    def __init__(self, one, two, three, four, five, *more):
        self.one= one
        self.two= two
        self.three= three
        self.four= four
        self.five= five
        self.more= more

Where more is a list and one to five are strings. I have a list of these items:

list_items = []
list_items.append(Item('Test','Test','Test','Test',more))

The dbus part looks like this:

@dbus.service.method('com.me.test', in_signature='', out_signature='a(sssssav)')
def get_all_items():
    return list_items

Is there an error in my signature or do I have to use a different data structure (tuples?) which can be marshalled?

Answer 1

You could alway use pickle or marshal and send your data as eg a byte-string. Else you could alternativly create your own DBus-Object by subclassing from dbus.service.Object . I would go with the former...
