I want to know how can i serialize with boost::serialization a two dimensions boost::multiarray.
how should i do that, the thing is that i am working in a network linux home and i have to find a way to be make that change in my own proyect not modificating the boost/multiarray.hpp. You will have to excuse my english i am from cuba. i have this code but i don't know how to call it inside a class were i already have a serialize methods for other parameters of the class, i also want to make an xml output file. #ifndef BOOST_MULTI_ARRAY_S11N_HPP #define BOOST_MULTI_ARRAY_S11N_HPP //For serialization #include <iomanip> #include <iostream> #include <fstream> #include <boost/archive/text_oarchive.hpp> #include <boost/archive/text_iarchive.hpp> #include <boost/archive/binary_oarchive.hpp> #include <boost/archive/binary_iarchive.hpp> #include <boost/serialization/split_free.hpp> //#include <boost/serialization/export.hpp> //For multi_array #include <boost/multi_array.hpp> namespace boost { namespace serialization { //----------------------------------------------------------------------------- template< class Archive, class T > void save( Archive & ar, const multi_array<T,2>& t, const unsigned int /* version */ ) { unsigned int rows = t.shape()[0]; unsigned int cols = t.shape()[1]; ar & rows & cols; for ( unsigned int i=0; i<rows; ++i ) { for ( unsigned int j=0; j<cols; ++j ) { ar & t[i][j]; } } } template< class Archive, class T > void load( Archive & ar, multi_array<T,2>& t, const unsigned int /* version */ ) { unsigned int rows, cols; ar & rows & cols; t.resize( boost::extents[rows][cols] ); for ( unsigned int i=0; i<rows; ++i ) { for ( unsigned int j=0; j<cols; ++j ) { ar & t[i][j]; } } } template<class Archive, class T> inline void serialize( Archive & ar, multi_array<T,2>& t, const unsigned int file_version ) { split_free(ar, t, file_version); } On 6/12/07, Matthias Troyer <troyer@phys.ethz.ch> wrote:

You will need to implement serialization support in boost::multiarray

You can do non-instrusive serialization support. Here is what I did for boost::bitset that I keep in a header file in my hobby project. To do something similar for boost/multiarray, you would implement these same three functions with the second parameter changed to match the multiarray, and change the body so that all the relevant bits are saved. namespace boost { namespace serialization { template <class Archive, size_t Nb> void save(Archive &ar, const std::bitset<Nb> &bs, const unsigned int version) { unsigned long i(bs.to_ulong()); ar << i; } template <class Archive, size_t Nb> void load(Archive &ar, std::bitset<Nb> &bs, const unsigned int version) { unsigned long i; ar >> i; bs = i; } template <class Archive, size_t Nb> void serialize(Archive &ar, std::bitset<Nb> &bs, const unsigned int version) { boost::serialization::split_free(ar, bs, version); } } }

I did take a look a year or so ago when the issue came up in a project, but we did not need it in the end. It seemed to me finally that an intrusive serialization is best, and you would need to modify boost/multiarray.hpp. Matthias On 12 Jun 2007, at 17:53, Alejandro Rubinos Carbajal wrote:
