Exposing a pointer in Boost.Python

Question

I have this very simple C++ class:

class Tree {
    public:
        Node *head;
};
BOOST_PYTHON_MODULE(myModule)
{

   class_(\"Tree\")
        .         


        

Answer 1

Of course, I find the answer ten minutes after asking the question...here's how it's done:

class_<Tree>("Tree")
    .add_property("head",
     make_getter(&Tree::head, return_value_policy<reference_existing_object>()),
     make_setter(&Tree::head, return_value_policy<reference_existing_object>()))
;
