Is it possible to initialize new object in constructor's initialization list and reference it?

Question

Client is the top class of DLL so I need to create and pass new Session object in it's initialization to create requestor and session should be assigned to same Session. Is it possible?

class Session
{
public:Session() {}

};

class Requestor
{
public: Requestor(const Session& session) {};
};

class Client
{
public:Client()
{
    Session newSession;
    requestor = Requestor(newSession);
}

private:
    Session session;
    Requestor requestor;
};

Answer 1

It is possible, but somewhat fragile in that the initialization order depends on the declaration order of the members. Provided these remain as in your example, you can simply do

class Client()
{
public:
    Client() : requestor(session) // session is implicitly default constructed
    {}
private:
    Session session;
    Requestor requestor;
};

Note: it isn't clear why you are instantiating a local Session object in your constructor. I am assuming that is a mistake.
