need help

[toto]

i have this class:

class Process : public Gob
{
private:
TotalAmount *Process::getTotalAmount( DetailList & dl );

public:
virtual void operator()(Invoice&);
};

what does the :: sign mean here ?

It means a syntax error.

i have this class:

{
private:
TotalAmount *Process::getTotalAmount( DetailList & dl );

public:
virtual void operator()(Invoice&);
};

Maybe you mean

private:
TotalAmount * getTotalAmount( DetailList & dl );

(a member function declaration) or

private:
TotalAmount (Process::*getTotalAmount)( DetailList & dl );

( pointer to member decalration).

Your syntax is half-way between the two. It is an error.

Don't you get a compilation error here that qualified name is not allowed in a
member declaration?

public:
virtual void operator()(Invoice&);
};

what does the :: sign mean here ?

It is the scope resolution operator.
TotalAmount *Process::getTotalAmount( DetailList & dl )
{
....
}
This would mean that Process class has a member function called getTotalAmount.
This is the definition of the member function.

so this would be equivalent to :

class Process : public Gob
{
private:
TotalAmount *getTotalAmount( DetailList & dl );

public:
virtual void operator()(Invoice&);
};


right ?

Please don't top-post.
Yes, this is syntactically correct.
Note that you have just declared and not defined the member functions yet.
You could define them within the class body (inline)-
TotalAmount *getTotalAmount( DetailList & dl )
{
....
}
or
Outside the class body
TotalAmount *Process::getTotalAmount( DetailList & dl )
{
....
}

No, your replies belong following the quotes. See how I've done it?
