[C++-sig] Wrapping method that returns const int& (boost::python)

[Abhishek Srivastava]

Does this works  for you??


class Foo
{
  public:
    const int& getX() const {return x;}
    void setX(const int& x_) {x = x_;}

  private:
    int x;
};

BOOST_PYTHON_MODULE(module)
{
  class_<Foo>("Foo")
    .def("getX", &Foo::getX, return_value_policy<return_by_value>())
  ;
}


With Regards,
Abhishek Srivastava

I have a simple test case:


class Foo
{
  public:
    const int& getX() const {return x;}
    void setX(const int& x_) {x = x_;}

  private:
    int x;
};


BOOST_PYTHON_MODULE(module)
{
  class_<Foo>("Foo")
    .def("getX", &Foo::getX)
  ;
}


The problem is that I cannot wrap getX and I get a compiler error. How
is it possible to wrap getX WITHOUT changing anything in Foo?

Thanks in advance!
