Detailed Description

template<unsigned int NFunc, template< unsigned int > class Func>
struct hit::details::CompiledGausFitCacheBaseStruct::InitializeFuncSumVector< NFunc, Func >

A helper class initializing the function vector.

Template Parameters

NFunc	the maximum number of base functions in a function
Func	the function encapsulating object
Others	other template parameters of the function object

This helper class provides a static function fill() that fills the function vector of the specified CompiledGausFitCacheBaseStruct with a sequence on NFunc+1 functions, of types Func<0, Others...>, Func<1, Others...>, ... up to Func<NFunc, Others...> included. Each function is actually wrapped by a ROOT's TF1. Func type is a class, and the actual function must be found in the member Func::eval. Also the Func class is required to have a NParams static constexpr member whose value is the number of parameters that theeval()` function takes.

The template FuncSum is implementing all these requirements.
