__gnu_para...t_selector(3)

🎀 NAME 🎀

hey bestie, welcome to the __gnu_para...t_selector(3) page from the Library Functions Manual ✨. This is __gnu_parallel::inner_product_selector — the selector for std::inner_product(), periodt. That's the whole name vibe: std::inner_product() selector.

✨ SYNOPSIS ✨

ok so real talk: it inherits generic_for_each_selector< It >.

🌸 Public Member Functions 🌸

• inner_product_selector (It b1, It2 b2) — constructor, taking b1 and b2 (begin iterators, more deets below).
• template<typename Op > T operator() (Op mult, It current) — the functor execution moment, taking a multiplication functor mult and an iterator current.

🫶 Public Attributes 🫶

• It begin1_iterator — begin iterator of first sequence.
• It2 begin2_iterator — begin iterator of second sequence.
• It finish_iterator — inherited; iterator on last element processed; needed for some algorithms (e. g. std::transform()).

🦋 Detailed Description 🦋

template<typename It, typename It2, typename T> struct
    __gnu_parallel::inner_product_selector< It, It2, T >

std::inner_product() selector — iconic behavior, honestly.

💖 Constructor & Destructor Documentation 💖

🎀 inner_product_selector 🎀

template<typename It , typename It2 , typename T >
    __gnu_parallel::inner_product_selector< It, It2, T
    >::inner_product_selector (It b1, It2 b2) [inline, explicit]

Constructor, bestie. It takes:

• b1 — Begin iterator of first sequence.
• b2 — Begin iterator of second sequence.

💅 operator() 💅

template<typename It , typename It2 , typename T > template<typename Op > T
    __gnu_parallel::inner_product_selector< It, It2, T >::operator() (Op
    mult, It current) [inline]

Functor execution — this is where it does the thing ✨.

Parameters:

• mult — Multiplication functor.
• current — Iterator referencing object.

Returns: Inner product elemental result. (slay.)
