Hi all,
I have a C++ library that needs to store in a hash map user's code,
that is, Python-extended objects. To make the C++ interface available to
Python, I use boost::python::wrapper, as stated in the tutorial
(http://www.boost.org/doc/libs/1_42_0/libs/python/doc/tutorial/doc/html/python/exposing.html#python.class_virtual_functions).
Because I store this extend objects, I need to tell Python that I've got a
reference on these objects.
A thread from 2007
(http://mail.python.org/pipermail/cplusplus-sig/2007-March/011790.html) states
there is a problem for this particular use case, but in the end, no solution is
given. So my question is the following: as of today, what is the correct way to
tell Python we hold a reference to Python extend objects of C++ classes, using
the boost::python::wrapper mechanism?
Thanks,
