Detailed Description

template<class Interpolator, template< class > class Bootstrap = QuantExt::IterativeBootstrap>
class QuantExt::PiecewiseOptionletStripper< Interpolator, Bootstrap >

Helper class to strip optionlet (i.e. caplet/floorlet) volatilities from the cap floor term volatilities of a CapFloorTermVolSurface.
