google.appengine.api.cmp_compat.total_ordering_from_cmp

Class decorator that fills in missing ordering methods from __cmp__.

google.appengine.api.cmp_compat.total_ordering_from_cmp(
    cls
)

This lets us take a class defined for Python 2's ordering system (using __cmp__) and use it with minimal changes — just a decorator — in Python 3.

This implementation is adapted from the Python 2 version of functools.total_ordering, which derives these methods from each other instead of from __cmp__.

Args
cls	The class to decorate.

Returns
The decorated class.
