c++ - Create and access frozenset with Boost Python -

i have c++ methods have std::set<std::string> argument or return value. map python frozenset (or regular set) there not seem straightforward way this. know how 1 may accomplish task.

unfortunately, standard indexing_suite boost.python not support std::set. there indexing_suite v2, works on stl containers. (http://mail.python.org/pipermail/cplusplus-sig/2009-july/014704.html)

it may not have made official distribution, can find asking around. (http://mail.python.org/pipermail/cplusplus-sig/2009-july/014691.html)

i found harder use original indexing_suite, might fit needs.

if not work, can manually wrap std::set<std::string> other class. std::set<std::string> python, can turn python set easily.

---

i think both of more work called though. here do:

first, wrap function in c++ 1 has same signature, stuffs returned data in std::vector<std::string> instead of std::set<std::string>. expose function rather original

now have data in python.

second, wrap c++ function in python function takes data in std::vector<std::string> , stuffs python set.

yes, rather silly design aesthetics point of view, , not performant code in world, gets going minimum of code, , robust.
