Structure functions in header file <ql/.../probabilitytraits.hpp>

[Amine Ifri]

Hi there,

I was recently using the bootstrapping classes to build all sorts of hazard rates curves from quotes of credit spreads in the market for a prototype of mine and came across the following functions in <probabilitytraits.hpp>:

Real HazardRate::minValueAfter(Size i, const C*c, bool validData) {…} and Real HazardRate::maxValueAfter(Size i, const C*c, bool validData) {…}

I was wondering whether the argument Size i in these two functions is redundant, as I can’t see its use anywhere in the source code for these two functions.

Thanks,
Amine

Hi Amine,

the traits classes will be used as template parameter and there it will be expected that the function has a particular signature.

Look at SurvivalProbability in the same file (probabilitytraits.hpp) for an example where Size i is used.

Cheers
Andres
