Hi,

I have a complex case I'm trying to work with. I may be doing this completely wrong so if there is a better design for this I'm always open for that. However for now I'm going to assume my particular problem can be solved.

There exists two classes: A and B. Class A is defined as such:

class A { public: template< typename Archive > void load( Archive& archive, unsigned int ) { archive & m_listOfB; }

private: std::vector<int> m_listOfInt; boost::ptr_vector<B> m_listOfB; };

And class B is defined roughly as:

class B { public: template< typename Archive > void load( Archive& archive, unsigned int ) { // Code isn't important here } };

Here's the problem:

For each B that is deserialized by A::load(), I need to pass in a reference to m_listOfInt. So, essentially the load() function in B would look something like this:

void load( Archive& archive, unsigned int, std::vector<int>& listOfInt ) { }

I was hoping boost.bind could be used somewhere, but I just don't see how. One way to solve the problem is to call B::load() explicitly with the extra parameter, but I don't think that's an appropriate solution. Any ideas on how to solve this? Or perhaps I'm trying to solve the wrong problem.

What's wrong with:

class A { public: template< typename Archive > void load( Archive& archive, unsigned int ) { archive & m_listOfInt; archive & m_listOfB; }

private: std::vector<int> m_listOfInt; boost::ptr_vector<B> m_listOfB; };

I'm guessing that the missing B::load code IS important. Jeff
