Re: [Boost-users] Problems with char* serialization

10 Apr 2008

      First of all, thank to everyone you for the help.
What actually I want to do is to serialize large floats arrays, float* not
std::vector, but I could evaluate to use std::vector instead of float*.

Thanks a lot!

Hi Ariel,
if you want to use char* to deal with text, I'd recommend to use
std::string instead, if you're interested in an array, you might want to
consider using a std::vector. If you can't do this for some reason,
here's some code which serializes a DREAL* (DREAL=double) and should
work similarly for char*:
friend class boost::serialization::access;
   template<class Archive>
   void save(Archive & ar, const unsigned int version) const
   {
     ar & num_labels;
     for (int i=0; i < num_labels; ++i)
     {
       ar & labels[i];
     }
   }
template<class Archive>
   void load(Archive & ar, const unsigned int version)
   {
ar & num_labels;
     if (num_labels > 0)
     {
       labels = new DREAL[num_labels];
       for (int i=0; i< num_labels; ++i)
       {
         ar & labels[i];
       }
}
   }
BOOST_SERIALIZATION_SPLIT_MEMBER();
Cheers,
Chris

Yes, but I am trying to serialize a char*, not a const char*. Is it
possible?
Thank you,

Yes, but in case of pointer to const char your primitive type
        is const char.
