Hello !
I am trying to serialize a a complex structure. One of the "variable" is a
2D Array (Cell** m_cells ) declared with pointers. I need to keep this data
structure as it is.
I have read some stuff about multi array with boost but found nothing to
serialize my Cell** m_cells.
Maybe one of you has the solution ....
Note1: using boost 1.41.0, g++ and ubuntu 9.04 ....
Note2: As you may understand while reading the code, I have in fact an
Array2D of PointAccumulator .... (Cell = PointAccumulator)
The part of code that is not correct .....
* template <class Archive> void serialize(Archive& ar, const unsigned int
version){
*ar & m_xsize & m_ysize &* m_cells;
}*
And raising this error:

Here is the code I use for my tests:
#include <iostream>
#include <iterator>
#include <algorithm>
#include <sstream>
#include <fstream>
#include
#include
using namespace std;
using namespace boost::archive;
using namespace boost::serialization;
/*
* point
*
*/
template <class T> struct point{
inline point():x(0),y(0) {}
inline point(T _x, T _y):x(_x),y(_y){}
T x, y;
friend class boost::serialization::access;
template <class Archive>
void serialize(Archive& ar, const unsigned int version){
ar & x & y;
}
};
/*
* PointAccumulator
*
*/
struct PointAccumulator{
typedef point<float> FloatPoint;
PointAccumulator(): acc(0,0), n(0), visits(0){}
PointAccumulator(int i): acc(0,0), n(0), visits(0){assert(i==-1);}
static PointAccumulator* unknown_ptr;
FloatPoint acc;
int n, visits;
friend class boost::serialization::access;
template <class Archive> void serialize(Archive& ar, const unsigned int
version){
ar & n & visits & acc;
}
};
/*

*/
template class Array2D{
public:
Array2D(int xsize=0, int ysize=0);
Array2D& operator=(const Array2D &);
Array2D(const Array2D &);
//~Array2D();
inline Cell& cell(int x, int y);
inline void print(){
cout << "Displaying array2D (x,y) --> (" << m_xsize << "," <<
m_ysize << ")" << endl;
for(int i=0;i
Array2D & Array2D::operator=(const
Array2D & g){
if (debug || m_xsize!=g.m_xsize || m_ysize!=g.m_ysize){
for (int i=0; i myArr2 =
loadFromFile("out.txt");
myArr2.print();
}
Thanks for the help !
