Hi,
i have a C++ class that i'm wrapping with boost::python:
class Foo {
// ...
const char *get_buffer();
size_t get_size() const;
// ...
};
I want to send this class through a thrift interface (which uses the
write() method to send the data to a file or a socket). For a few days now
i'm trying to implement this. By now i understand that i have to implement
the buffer protocol, and i know that i can create a buffer with
boost::python (read-only access is sufficient):
inline object as_buffer(const Foo &f) {
return object (handle<> (PyBuffer_FromMemory ((void*)f.get_buffer(),
f.get_size())));
}
(This is based on an email from 2009 that i found in this mailing list's
archive.)
But i do not know how to glue it together to form a full module. This is
how the module looks right now:
BOOST_PYTHON_MODULE(Foo)
{
class_<Foo, boost::noncopyable>("Foo",
init<int32_t, bool>())
.def("add", afn)
.def("finalize", &Foo::finalize)
.def("empty", &Foo::empty)
.def("clear", &Foo::clear)
;
}
How can i include that buffer conversion?
Thanks a lot,
Christoph
