Hello,
I am aware about the possibility to register converters to- and from-
Python, which enable the implicit conversions between user-defined and
build-in types in Python.
My question is different: Is it possible to use Boost.Python to
convert existing data structures from C++ to Python?
Simple example:
//C++ struct:
struct Foo {
int x, int y;
};
class_<Foo>("Foo")
.def_readwrite("x", &Foo::x)
.def_readwrite("y", &Foo::y);
//instance of Foo
Foo foo = {1, 2};
Now I would like to pass foo object to some Python method. Obviously I
need to create a Python version of this object.
Python is aware of the Foo definition thanks to Boost.Python, but
still, is there any other method of transferring the data than the
one, which uses some glue function which creates a Python Foo instance
based on all members of C++ foo passed separately to it? As far as I
am aware, Python converters are not intended to help here.
The docs claim, that BOOST::PYTHON::Object can not be used as a
replacement of PyObject, i.e. e.g. it can't be passed to some Python
function and used inside of it. Hence I assume it won't be helpful in
this case.
thanks!
