__GNU_PARALLEL::__REPLACE_SELECTOR(3)

✨ NAME ✨

__gnu_parallel::__replace_selector< _It, _Tp > — the std::replace() selector, bestie 💖

okay so real quick, this is a page from the Library Functions Manual, section 3, and it's all about one lil struct that lives in the GNU parallel universe. it does exactly one job and it does it gorgeously.

---

🌸 SYNOPSIS 🌸

#include <for_each_selectors.h>

it inherits from __gnu_parallel::__generic_for_each_selector< _It > — so all that base-class energy is coming along for the ride, no cap. 🧬

🎀 Public Member Functions

• __replace_selector (const _Tp &__new_val) — the Constructor. builds the thing, sets the vibe.
• bool operator() (_Tp &__v, _It __i) — Functor execution. this is the part that actually goes 🏃‍♀️

🎀 Public Attributes

• const _Tp & __new_val — Value to replace with. the glow-up target, literally.
• _It _M_finish_iterator — _Iterator on last element processed; needed for some algorithms (e. g. std::transform()). she's the lil bookmark that keeps track of where we ended up 🦋

🦋 Detailed Description 🦋

template<typename _It, typename _Tp>
    struct __gnu_parallel::__replace_selector< _It, _Tp >"std::replace()
    selector.

yes that stray little " is literally in there, i am not playing, i am not editorializing, i am just the messenger 🙈

so like, the whole point: it's a selector for std::replace(). template over _It (your iterator type) and _Tp (your value type), and it slots into the parallel machinery so replacing stuff can happen across your whole range. periodt. 💅

💅 Constructor & Destructor Documentation 💅

template<typename _It, typename _Tp> __gnu_parallel::__replace_selector< _It, _Tp >::__replace_selector (const _Tp & __new_val) [inline], [explicit]

Constructor. she's [inline] AND [explicit] — no sneaky implicit conversions around here, we have standards ✨

Parameters

• __new_val — Value to replace with.

References __new_val.

---

🔥 Member Function Documentation 🔥

template<typename _It, typename _Tp> bool __gnu_parallel::__replace_selector< _It, _Tp >::operator() (_Tp & __v, _It __i) [inline]

Functor execution. this is where the magic happens, bestie — you hand her a value and an iterator and she does the thing. 🪄

Parameters

• __v — Current value.
• __i — iterator referencing object.

References __new_val.

👑 Member Data Documentation 👑

template<typename _It, typename _Tp> const _Tp& __gnu_parallel::__replace_selector< _It, _Tp >::__new_val

Value to replace with. that's it, that's the data. simple, iconic, effective. 🍓

Referenced by __replace_selector(), and operator()().

template<typename _It> _It __gnu_parallel::__generic_for_each_selector< _It >::_M_finish_iterator [inherited]

_Iterator on last element processed; needed for some algorithms (e. g. std::transform()). note the [inherited] tag — this one's not hers originally, she got it from __generic_for_each_selector< _It >. sharing is caring. 🫶

💀 a gentle PSA from me to you: this page is Doxygen-generated, so the prose is giving "robot wrote it at 3am". i have simply fixed the aura. the facts? untouched. every template param, every bracket, every [inline], every [inherited] — all still exactly where they were. 🔥

okay bye bestie, go replace some values 💖✨🎀🦋🌸💅🫶
