Hello everybody, I've read the rationale for only allowing const trackable objects, but here is my problem : I want to serialize the following class : class C : boost::noncopyable { public: void setData(string s) {data = s;} //... }; int main() { C c; c.setData("Hello world"); vector <C*> v; v.push_back(&c); //... ar << c << c; } To have a c with meaningfull data, it cannot be const. I cannot create a local object that is a copy of the object (it is noncopyable) I do not think making the object untracked would be a good idea in this case (I might be wrong ?) So far, the best way I found to be able to serialize this object is : C const & cForSerialize = c; ar << cForSerialize << cForSerialize; But I do not think this is really elegant code. Is there a better alternative ? -- Loïc
