[Quantlib-dev] Non copyable curves.

[Simon I. <Sim...@st...>]

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);

        }
