[Boost-users] variant over base and derived classes

hello, How to determine the actual type of the object stored in a variant? struct S { virtual ~S() {} }; struct Deriv1 : public S { virtual ~Deriv1() {} }; struct Deriv2 : public S { virtual ~Deriv2() {} }; struct Deriv3 : public Deriv2 { virtual ~Deriv3() {} }; typedef boost::variant my_variant_t; Deriv3 d3; struct print_type: public boost::static_visitor<> { template <typename T> void operator()(const T&) const { std::cout<< typeid(T).name() <
