Module copy_reg

Helper to provide extensibility for pickle/cPickle.

This is only useful to add pickle support for extension types defined in C, not for instances of user-defined classes.

Function Details

[hide private]

_slotnames(cls)

Return a list of slot names for a given class.

This needs to find slots defined by the class and its bases, so we can't simply return the __slots__ attribute. We must walk down the Method Resolution Order and concatenate the __slots__ of each class found there. (This assumes classes don't modify their __slots__ attribute to misrepresent their slots after the class is defined.)

remove_extension(module, name, code)

Unregister an extension code. For testing only.
