Non copyable curves.

Hi guys,

 

Why have all curves recently been derived from boost::noncopyable?

 

I’ve been copying yieldcurves (in external code) – and it has been working perfectly if you implement a copy constructor for the PiecewiseYieldcurve class that initializes the bootstrapper for the current curve (in the code I submitted – shown below). Surely this makes more sense than completely disabling copying?

 

 

 

//copy constructor

        PiecewiseYieldCurve(const this_curve& o)

            : base_curve(o), instruments_(o.instruments_), turnOfYearEffect_(o.turnOfYearEffect_),

            accuracy_(o.accuracy_), latestReference_(o.latestReference_), turnOfYear_(o.turnOfYear_),

            bootstrap_(o.bootstrap_) {

                setTurnOfYear();

                registerWith(turnOfYearEffect_);

                bootstrap_.setup(this);

        }
