[QUOTE="Rune Allnor, post: 3950363"]
Hi all.

I have this class that contain a number of instances of other classes:

class A {...};

class B {...};

class Spider {
public:
    Spider(const *A, const *B);
private:
   Spider(){};
};

class BigClass{
public:
    BigClass() : A_(), B_()
    {
         Spider_(&A_,&B_);
    }
private:
   A A_;
   B B_;
   Spider Spider_;
};

The A and B classes contain data, while the Spider class
is supposed to maintain certain connections / relations
between the two collections of data.

The problem here is the constructor of BigClass: Both A_ and
B_ have to be fully constructed before the constructor of Spider_
can start. Even if the declarations above indicate that it is
sufficient that the adresses of A_ and B_ have been determined
at the point when Spider::Spider(...) is called, the operations
inside
Spider::Spider(...) requires that A_ and B_ have been fully
constructed.

Is there any way to ensure that things happen in the required
sequence?
