The program run ok when I compile it with mingw, but if I compile it
use vc71, the program will crash when excute "pbb->Load( ifs );".
Thinks!
code:
//----------------------------------------------------------------------------
#include <string>
#include <iostream>
#include <fstream>
#include
#include
//----------------------------------------------------------------------------
using namespace std;
//----------------------------------------------------------------------------
class A
{
private:
friend class boost::serialization::access;
template<class Archive>
void serialize(Archive & ar, const unsigned int version)
{
ar & a;
ar & b;
}
public:
int a;
int b;
void Load( std::ifstream& ifs )
{
boost::archive::text_iarchive ia(ifs);
ia >> *this;
}
void Save( std::ofstream& ofs )
{
boost::archive::text_oarchive oa(ofs);
const A& refa = *this;
oa << refa;
}
};
//----------------------------------------------------------------------------
class B
{
private:
friend class boost::serialization::access;
template<class Archive>
void serialize(Archive & ar, const unsigned int version)
{
ar & ms;
ar & a;
}
public:
void Load( std::ifstream& ifs )
{
boost::archive::text_iarchive ia(ifs);
ia >> *this;
}
void Save( std::ofstream& ofs )
{
boost::archive::text_oarchive oa(ofs);
const B& refb = *this;
oa << refb;
}
public:
B( const string& s ) : ms( s ){}
void print(){ cout << ms << endl; }
private:
string ms;
A a;
};
//----------------------------------------------------------------------------
int test_TestStorage()
{
// Save
A* pa = new A;
pa->a = 3;
pa->b = 5;
B* pb = new B( "this is test B" );
std::ofstream ofs( "all.out" );
pa->Save( ofs );
pb->Save( ofs );
delete pa;
delete pb;
ofs.close();
// Load
A* paa = new A;
B* pbb = new B( "" );
std::ifstream ifs( "all.out", std::ios::binary );
paa->Load( ifs );
pbb->Load( ifs );
cout << "A: " << paa->a << " " << paa->b << endl;
pbb->print();
delete paa;
delete pbb;
return 0;
}
//----------------------------------------------------------------------------
int main( void )
{
test_TestStorage();
return 0;
}
2007/12/31, Mahesh Venkitachalam :
In my application, I am am saving 2 objects into the same archive and then
reading
them back correctly in the same order - so it is possible. Maybe you could
post how
you implemented "Load" and "Save" and I can try to help you.
Mahesh
