Hi all, I found that uBLAS doesn't have Serialization support built in. So in my code, I do the following: ===== snip ===== class A { typedef boost::numeric::ublas::c_vector container_t; public: // Other member functions... private: friend class boost::serialization::access; template <typename Archive> void serialize(Archive &ar, unsigned int version) { container_t::pointer data = data_.data(); container_t::value_type (*p)[3] = reinterpret_cast(data); ar & boost::serialization::make_nvp("data", *p); } private: // The data field to be serialized container_t data_; }; ===== snip ===== While this code seems to be working on my machine, there is reinterpret_cast<> in place in order to grab the content of the vector, as you can see. So my question is: Is this way of performing serialization safe/ portable/ etc.? Any idea?
