[Quantlib-dev] How to correctly Extend swig PiecewiseYieldCurve.i

[Irakli M. <ima...@ho...>]

I tried to add thrd parameter Bootstrap type to  export_piecewise_curve like 
this

%define export_piecewise_curve(Name,Base,Interpolator,Bootstrap)

and then
export_piecewise_curve(PiecewiseFlatForward,ForwardRate,BackwardFlat,IterativeBootstrap);

Code produced by swig looks like this

SWIGINTERN PiecewiseFlatForwardPtr *new_PiecewiseFlatForwardPtr__SWIG_0(Date 
const &referenceDate,std::vector< boost::shared_ptr< RateHelper > > const 
&instruments,DayCounter const &dayCounter,std::vector< Handle< Quote > > 
const &jumps=std::vector< Handle< Quote > >(),std::vector< Date > const 
&jumpDates=std::vector< Date >(),Real accuracy=1.0e-12,BackwardFlat const 
&i=BackwardFlat()){
            return new PiecewiseFlatForwardPtr(
                new 
PiecewiseYieldCurve<ForwardRate,BackwardFlat,IterativeBootstrap>(
                                                 referenceDate,instruments,
                                                 dayCounter, jumps, 
jumpDates,
                                                 accuracy,i));
        }

And compiler curses

I understand that IterativeBootstrap itself is a template class and that’s 
probably the reason, but in test suite similar code compiles fine
testCurveConsistency<ZeroYield,Cubic,IterativeBootstrap> ...
