Re: [Boost-users] [python] raw pointer data members

Hello Boosters,

I'm trying to use Boost Python that way:

  template<class Key>   struct Node   {      Node(Key key): key(key) {}      Node* parent;      Node* left;      Node* right;      Key key;   };

.....

 BOOST_PYTHON_MODULE(tree)   {      class_<Node>("Node", init<int>())         .def_readwrite("parent", &Node::parent)         .def_readwrite("left",   &Node::left)         .def_readwrite("right",  &Node::right)         .def_readwrite("key",    &Node::key);   };

But then I can't use parent, left and right properties in Python code. Is there a way to convert these raw pointers to common object reference in Python?

I do not know what the 'proper' way is, but any time I had that issue I either changed all Node* to shared_ptr<Node> if I had access to change the class, or I added wrapper set/get functions if I did not.
