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,

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
