[C++-sig] Boost converter for passing std::vector object by reference into a function??

[DeVico, Mike]

Hello,

I would like to wrap a class that looks like below (taken from an example I found on another site)

#include <boost/python.hpp>
#include <boost/python/suite/indexing/vector_indexing_suite.hpp>
#include <boost/python/suite/indexing/map_indexing_suite.hpp>

typedef std::vector<std::string> MyList;
class MyClass {
public:
  MyList myFuncGet()
  {
     return MyList();
  }
  void myFuncSet(MyList& list)
  {
    list.push_back("Hello");
  }
  //       stuff
};

BOOST_PYTHON_MODULE(MyModule)
{
    class_<MyList>("MyList")
        .def(vector_indexing_suite<MyList>() );

    class_<MyClass>("MyClass")
        .def("myFuncGet", &MyClass::myFuncGet)
        .def("myFuncSet", &MyClass::myFuncSet)
        ;
}

However, this is what I get when I try to use it from python:

Python 2.7.2 (default, Jun 12 2011, 14:24:46) [MSC v.1500 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> from MyModule import *
>>> mc = MyClass()
>>> p = []
>>> mc.myFuncSet(p)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
Boost.Python.ArgumentError: Python argument types in
    MyClass.myFuncSet(MyClass, list)
did not match C++ signature:
    myFuncSet(MyClass {lvalue}, std::vector<std::string, std::allocator<std::string> > {lvalue})
>>>

I know I'm missing a converter function, but I'm new to boost and I don't know what the converter
should  look like in this case.

I've found lots of working examples of how to return a vector, but I want to be able to pass the vector
into the function by reference and modify it.

I would really appreciate it if someone could complete the example by adding the necessary converter
code.

Thanks in advance.
