I believe you can do what you want like this:

#include <boost\shared_ptr.hpp>

#include <boost\weak_ptr.hpp>

class A;

class B;

typedef boost::shared_ptr<A>    spA;

typedef boost::shared_ptr<B>    spB;

typedef boost::weak_ptr<A>      wpB;

class A

{

// ...

   spB m_b;

};

class B

{

    wsB                 m_wpParent;

// ...

    std::vector<spA>    m_a;

};

I hope this helps,

Subject: [Boost-users] Smart pointers

Hi all

Suppose I have two classes A and B like those ones :

Typedef

class A
{
   // ...
   B *m_b;
};

class B
{
   // ...
   std::vector<A *> m_a;
};

m_b is used to know who is the parent of the object.

I would like to use smart pointers. How can I do this ?

Thanks in advance
