I have a problem with serialization, and I do not know how to solve it. Time
to serialize the class a lot of growing when I do it in a loop. The first
iteration takes about 40 ms, for example, but any other takes about 400 ms.
class NODE
{
public:
NODE(){}
NODE* add(NODE* node)
{
children.push_back(node);
return node;
}
~NODE()
{
for(vector<NODE*>::const_iterator it = children.begin(); it !=
children.end(); ++it)
{
delete *it;
}
}
vector<NODE*> children;
private:
friend class boost::serialization::access;
template <typename Archive>
void serialize(Archive &ar, const unsigned int version)
{
ar & children;
}
};
void save(NODE* main)
{
std::ofstream stream("test", std::ios::binary);
boost::archive::binary_oarchive oa(stream, boost::archive::no_header);
oa << main;
}
int main()
{
boost::timer t;
NODE* main(new NODE());
for (int i=0; i<2000;i++)
{
NODE* subnode = main->add( new NODE());
for (int k=0; k<20; k++) subnode->add( new NODE());
}
for (int i=0; i<4; i++)
{
t.restart();
save(main);
cout<<"serialize: "<
