Save/Store whole class (or another object) in a file

[alexLIGO at googlemail.com]

Hi,

thanks for the reply,but unfortunately this does not work with the type
of classes I am dealing with. When trying to pickle the class I get the
following error:

 File "/usr/lib/python2.4/copy_reg.py", line 76, in _reduce_ex
    raise TypeError("a class that defines __slots__ without "
TypeError: a class that defines __slots__ without defining __getstate__
cannot be pickled

So there is something missing in this class? Or any other idea how to
do this?

Alex
