boost-serialization

问题 As this link stated for defining traits for a template class we should define it manually or we extract our class from the trait class. But I want to make this process automatically, for this reason inspired from BOOST_CLASS_TRACKING I wrote the blow code: #include<boost/preprocessor/tuple/enum.hpp> ... #define FOO_CLASS_TRACKING(E, PARAMETER_TUPLE, ...) \ namespace boost { \ namespace serialization { \ template<BOOST_PP_TUPLE_ENUM(PARAMETER_TUPLE)> \ struct tracking_level< __VA_ARGS__ > \ {

问题 I'm looking for a (working) example for externally serializing a class-structure in a DLL. Currently I'm not able to find any examples for that. The Boost documentation is just stating some macros, the forums and newsgroups are just discussing specific problems with their solutions. So I'm asking for an example for (externally) serializing a class-structure like the following. Along with the class-code I added some code of mine for serializing (which does not work, see bottom for error

问题 I have recently been using save_construct_data() and load_construct_data() when I need to serialize an object without a default constructor. Since it doesn't make sense to do: MyObject a; // can't do this because there is no default constructor archive >> a; we must do: MyObject* aPointer; archive >> a; which calls load_construct_data() before serialize() . However, of course this only works if the object was serialized using save_constructor_data() which is only called if it is written as a

问题 I have 3 classes ("Leader", "Researchers", "Workers") which all derive from a base-class "Team". I have a class "Project" which contains a vector of pointers to different Teams. I use all of the following headers, in this order, in all of my class declarations: #include <sstream> #include <boost/archive/text_oarchive.hpp> #include <boost/archive/text_iarchive.hpp> #include <boost/serialization/serialization.hpp> #include <boost/serialization/export.hpp> #include <boost/serialization/vector

问题 I am using the boost example code to store a vector of pointers of objects in a file. My vector is: class VOMC{ public: vector<State*> vomc; ... ... private: friend class boost::serialization::access; template<class Archive> void serialize(Archive & ar, const unsigned int version) { ar & vomc; } } This gives me the following error(among few more): /usr/local/include/boost/serialization/access.hpp:118:9: error: ‘class State’ has no member named ‘serialize’ The error makes is probably telling

问题 When trying to save the database using boost serialization, I encounter the segfault that I could not resolve. Would you please help? Any suggestion is greately appreciated. I've pinned down the statement below as the culprit but not sure of how to resolve it oa << *this; My code section is below: template<class Archive> void nDB::serialize(Archive &ar, const unsigned int version) { ar & _LAYERS; ar & _MACROS; ar & _MODULES; ar & _INSTS; } void nDB::save_db(string filename) { std::ofstream

问题 I currently have a stl:list, which contains some base objects and some derived classes as well. I can load and save this list without any problems. With the BOOST_CLASS_EXPORT(...) macro, everything is working properly, until i add the following: -------------------------------------------------------------------------------------- I need some objects which contain pointers of other objects in the list. (To stop beeing so abstract: These are some "Game-Objects" and they have some References

问题 I currently develop a server application which has to receive serialized data from clients, deserialize it and finally process it. The serialized data is sent in form of an array of chars. My problem is that my application can be easily broken by sending invalid data to it. So I wanted to ask whether it's possible to check a string(-stream) and see whether it's good for (de-)serialization (e.g. whether it has a valid signature) before trying to get data from it. By the way: as the title

问题 Please help me deserialize a derived class to base-class pointer. I attach the complete source code example. request.hpp (no pair cpp file) #ifndef REQUEST_HPP #define REQUEST_HPP #include <memory> #include <string> #include <boost/archive/xml_oarchive.hpp> #include <boost/archive/xml_iarchive.hpp> namespace demo { namespace common { class request { public: static const int INVALID_ID = -42; request() : id_(INVALID_ID), timestamp_(0), source_ip_("unknown") {}; request(int id, long timestamp,

问题 I have some code that I want to build. The code uses boost::ptr_map class to serialize certain objects. I have Visual Studio 2008 with boost1.38 and I am getting following error from compiler. I wonder if any one else has seen any thing like this. C2039: 'serialize' : is not a member of 'boost::ptr_map' Looks like some reference is missing and I wonder what it is, I don't see any boost/serialization/ptr_map. I have Googled a lot and nothing has proved to be viable. I have created a sample
