An interesting topic which I've yet to find time to address. You're trying to serialize a pointer to a function. This is not implemented within the library. I would suggest a couple of ideas. Make each f1, f2... a function object. Make a boost::variant<f1, f2, ...> and serialize that. The library already supports serialization of variants. Another idea would be to dervive all function objects from a common base struct fbase { virtual void operator()(int a) = 0; // makes fbase polymorphic } and serialize through a base class pointer struct foo { fbase * f; std::vector<fbase *> functors_; void init(){ functors_.pushback(& f1...); }; Robert Ramey Igor R wrote:
Hello,
Is it possible to serialize the following class:
struct foo { void f1(int a) {} void f2(const std::string& s) {}
void init() { using boost::bind; functors_.push_back(bind(&foo::f1, this, 1)); functors_.push_back(bind(&foo::f2, this, "test")); }
std::vector<boost::function<void(void)> > functors_; };
That is, I'd like save the functors, in order to run them later, when the object is loaded from the archive.
A straightforward attempt fails:
struct foo { //...... friend class boost::serialization::access; template<class Archive> void serialize(Archive &ar, const unsigned int version) { ar & BOOST_SERIALIZATION_NVP(functors_); } };
