πŸ’– NAME πŸ’–

__gnu_parallel::__find_if_selector β€” bestie, this lil icon tests a predicate on a single element, and it's the one doing the heavy lifting for std::find() and std::find_if (). (yes the space before the parens is canon, we don't question the ancestors ✨)

(also hiii, this whole page lives in the Library Functions Manual, just so u know what you're reading 🫢)


🌸 SYNOPSIS 🌸

#include <find_selectors.h>

It inherits from __gnu_parallel::__generic_find_selector β€” so it's giving nepo baby but make it templates πŸ’…

  • template<typename _RAIter1, typename _RAIter2, typename _Pred> std::pair< _RAIter1, _RAIter2 > _M_sequential_algorithm (_RAIter1 __begin1, _RAIter1 __end1, _RAIter2 __begin2, _Pred __pred) β€” the corresponding sequential algorithm on a sequence, like the chill non-parallel version of the whole vibe
  • template<typename _RAIter1, typename _RAIter2, typename _Pred> bool operator() (_RAIter1 __i1, _RAIter2 __i2, _Pred __pred) β€” the test on one position, one single spot, very demure very mindful

πŸ¦‹ Detailed Description πŸ¦‹

Test predicate on a single element, used for std::find() and std::find_if ().

That's it, that's the whole thesis. It's a tiny little worker bee 🐝 that checks one element against your predicate so the parallel machinery can go feral across a whole range. no cap.

πŸ’œ _M_sequential_algorithm

template<typename _RAIter1, typename _RAIter2, typename _Pred> std::pair<
    _RAIter1, _RAIter2 >
    __gnu_parallel::__find_if_selector::_M_sequential_algorithm (_RAIter1
    __begin1, _RAIter1 __end1, _RAIter2 __begin2, _Pred __pred) [inline]

Corresponding sequential algorithm on a sequence. lowkey the "do it the normal way" backup plan πŸ”₯

Parameters β€” okay so here's the tea:

  • __begin1 β€” Begin iterator of first sequence. like the starting line of the first lineup 🏁
  • __end1 β€” End iterator of first sequence. the finish line, bestie, it does not include it, iykyk
  • __begin2 β€” Begin iterator of second sequence. second sequence's starting line, iconic
  • __pred β€” Find predicate. the vibe check itself πŸ’…

References std::make_pair() β€” it's literally calling that, not me guessing, fr fr.


πŸŽ€ operator()

template<typename _RAIter1, typename _RAIter2, typename _Pred> bool
    __gnu_parallel::__find_if_selector::operator() (_RAIter1 __i1, _RAIter2
    __i2, _Pred __pred) [inline]

Test on one position. just one. singular. main character energy on a single index πŸ‘‘

Parameters β€” more tea, sip slowly:

  • __i1 β€” _Iterator on first sequence. (yes that leading underscore is in the original, we keep it exactly, no editing βœ‹)
  • __i2 β€” _Iterator on second sequence (unused). not me being emotionally unavailable but make it a parameter πŸ™ˆ
  • __pred β€” Find predicate. the actual test, the moment of truth ⭐
heads up bestie: __i2 is straight up unused here. don't come for me, that's just what the docs say, and we report the facts even when they're a little goofy 😭

🌈 Author 🌈

Generated automatically by Doxygen for libstdc++ from the source code. so no human to thank, it just spawned like that 🧚


and that's the whole page, periodt πŸ’– no fancy version-and-date line at the bottom beyond the classic libstdc++ footer energy β€” that's the source/version stamp this page rocks, courtesy of the libstdc++ crew and their automatic Doxygen generation. stay slay, go find your elements, and remember: predicate on one element, always. bye bestie 🫢✨
