Python Tuple in Java XMLRPC

Question

I'm trying to pass python tuple over java xmlrpc. Here is library what I'm using: XMLPRC Java Libray

I'm using odoo framework on server and api. I want to pass argument which will looks like:

[(4,7),(4,8)]

I'm able to pass following structure:

[[4,7],[4,8]]

which is clearly array inside array like:

new Object[]{new Object[]{4,7},new Object[]{4,8}}

The problem is there is no tuple in java. What I absorb is how to transform this structure:

This [4,8] to This(4,8)

It is some kind of serialization issue what don't know how to resolve it and pass expected python structure.

Answer 1

Is there a problem with [[4,7],[4,8]] ? Most python operations don't differ tuples from actual lists. And in Odoo even less. I think that this is the proper way to send a list of tuples through languages that does not implement tuples. Tuple is not a key, value thing. You can have (a, b, c) which is a tuple. That is somewhat similar to [a, b, c]. You can iterate on both. You can get their value through indexes (if both were stored in a element variable, getting a from it would be element[0] for them both).

So if you have a problem, I don't think it's about tuples and you did not answer the comment asking if there is an error on the XMLRPC call. My guess is there is no error. And if there is an error, I'm sure it's not about tuples.
