[Boost-users] [Python] Custom getattr with different CallPolicy for different return values

4 Jan 2017

      Hi,

I would like to custom __getattr__ for my class such that for some
attributes, an internal reference is returned, and for others, a new object
is returned.

I cannot hardcode the attributes as they are dynamic.

I started writing something like:

boost::python::object myGetAttr(boost::python::object obj, std::string
const& attr)
{
   MyObj* mobj = boost::python::extract(obj)();
    if (attr == "internal_ref")
    {
        MyRef* refObj = mobj->getInternalRef();
        // how do I return this?
    }
    else
    {
        MyValueObj obj = mobj->getValueObj();
        // how do I return this?
    }
}

class_
   ("MyObj", no_init)
   .def ("__getattr__", &myGetAttr, ???what_should_I_put_here???)
;

However, I am not able to get this to work. Any suggestions?

Krishnan
