The copy_reg module provides support for the
cPickle modules. The
copy module is likely to use this in the
future as well. It provides configuration information about object
constructors which are not classes. Such constructors may be factory
functions or class instances.
- constructor (object)
Declares object to be a valid constructor.
- pickle (type, function[, constructor])
Declares that function should be used as a ``reduction''
function for objects of type or class type. function
should return either a string or a tuple. The optional
constructor parameter, if provided, is a callable object which
can be used to reconstruct the object when called with the tuple of
arguments returned by function at pickling time.
