Subject: [Boost-users] Smart pointers

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

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 ?

[Nat] Without thinking about it too hard...

My first implementation would use std::vector< boost::shared_ptr<A> > for m_a (parent object responsible for lifespan of its children) and boost::weak_ptr<B> for m_b (child object not responsible for lifespan of its parent).
