Re: [Boost-users] Deriving Serialization classes

????

a) But I'm deriving it from text_archive_imp

b) what? I didn't understand.. As I said the binary serialization is
working fine

c) Onde again what do you mean?? How can I derivate the serialization classes??

I've tried the following code to, but with the same error:

class TextArchiveO : public IArchive,
 // don't derive from text_oarchive !!!
 public boost::archive::text_oarchive_impl<TextArchiveO>
{
public:
 TextArchiveO(std::ostream & os, unsigned flags = 0) :
   boost::archive::text_oarchive_impl<TextArchiveO>(os, flags)
   {}

   ~TextArchiveO(){}

   virtual void Serialize(int& t) { *this & BOOST_SERIALIZATION_NVP(t); }
   virtual void Serialize(bool& t) { *this & BOOST_SERIALIZATION_NVP(t); }
};

class TextArchiveI : public IArchive,
 // don't derive from text_oarchive !!!
 public boost::archive::text_iarchive_impl<TextArchiveI>
{

public:
 TextArchiveI(std::istream & is, unsigned flags = 0) :
   boost::archive::text_iarchive_impl<TextArchiveI>(is,flags)
   {}

   ~TextArchiveI(){}

   virtual void Serialize(int& t) { *this & BOOST_SERIALIZATION_NVP(t); }
   virtual void Serialize(bool& t) { *this & BOOST_SERIALIZATION_NVP(t); }
};
