[boost] help

[柯猛]

Hi:   I'm now use the boost.python,and want to write my own converter. In the last version,I can write like this:   #include <boost/python/class_builder.hpp> namespace python = boost::python; BOOST_PYTHON_BEGIN_CONVERSION_NAMESPACE inline AsnInt from_python(PyObject* p, python::type<const AsnInt&>) {  return AsnInt(from_python(p, python::type<int>())); } inline AsnInt from_python(PyObject* p, python::type<AsnInt>) {     return from_python(p, python::type<const AsnInt&>()); } inline PyObject* to_python(const AsnInt& ai) {     return PyInt_FromLong((AsnIntType)ai); } BOOST_PYTHON_END_CONVERSION_NAMESPACE     In this new version, what can I do for the same work? Please give me some examples, Thank you very much!                                                                   kemeng
