So, my original question stands -- it is even possible to make boost::any serializable?
I've spent a few minutes looking at boost::any and don't see any obvious way to do it in a general way. If it is possible, it would only be so by depending on or expanding upon implementation of serialization. So, what can I suggest? Here are some very preliminary thoughts. The difficulty in serializing boost::any is that we only know which type is being serialized at runtime. If we know the possible types that our instance of boost::any might contain we might be able to use something like: struct my_class { boost::any m_any; ... }; template<class Archive> void my_class::save(Archive & ar, const unsigned int version){ // define which types we think we will be using // (be prepared for bad_anycast exception); boost::variant<int, char, bool> v = m_any; ar << v; } template<class Archive> void my_class::load(Archive & ar, const unsigned int version){ // define which types we think we will be = m_any; boost::variant<int, char, bool> v; ar >> v; m_any = v; } This is merely speculative so i have no idea whether it would really work or not.
