[Boost-users] Wrapper to C++ Lists using Python Boost

Hi all
           I am relatively new to python boost and am trying to wrap a list
of pairs using an iterator.

In the Public section I have

 namespace sky{

     class FindNextMask{
     public:
         FindNextMask() {};

         FindNextMask(int i):iter(i){}
         bool operator()(const pair<int,string>& p)const{
         if (iter <= p.first)
         return true;
        else
       return false;
        }
     private:
        int iter;
         };

Then in another class say S

 class S {
     private:
      list<pair<int,string> > A;
      }

I am unable to find a solution to this. Any help in this context would be
appreciated. I know to write wrappers for pairs and vectors but I do not
understand how to extend this to C++ lists and connect it with iterators
and operators.

class_<std::vector<std::pair<double, double> > >("VectorOfPairs")
            .def(vector_indexing_suite<std::vector<std::pair<double,double>
> >());
    class_<std::pair<double, double> >("DoublePair") // Wrapper for a pair only
            .def_readwrite("first", &std::pair<double, double>::first)
            .def_readwrite("second", &std::pair<double, double>::second);

Kind Regards
K.V.
