Detailed Description

template<typename T, size_t N, size_t I>
struct impl::MakeArray< T, N, I >

Helper template to initialize std::array compile-time.

Idea is that it "loops" over all reco::TrackBase::TrackAlgorithm enumerators from end to beginning. In each "iteration", the order priority is obtained from impl::algoPriorityOrder array, and the priority is added to a parameter pack. When the beginning is reached (termination condition is a partial specialization, see below), the std::array is initialized from the parameter pack. The "looping" is implemented as recursion.

Template Parameters

T	value_type of the std::array
N	Size of the std::array
I	Current index
