__GNU_PARALLEL::__TRANSFORM1_SELECTOR(3cxx)

πŸ’… __gnu_parallel::__transform1_selector< _It > β€” the whole page, bestie

okay so real talk, this is a page from the libstdc++ docs, manual section (3cxx), and honestly? it's a little cutie. Let's get into it 🫢


✨ NAME ✨

__gnu_parallel::__transform1_selector< _It > β€” it's the std::transform() __selector, the one input sequence variant. that's the whole vibe. one sequence in, no cap πŸ’…


🌸 SYNOPSIS 🌸

first thing you gotta do, literally the entry fee:

#include <for_each_selectors.h>

and it inherits from __gnu_parallel::__generic_for_each_selector< _It > β€” so it's got the family genes, iykyk 🧬

πŸŽ€ Public Member Functions

  • template<typename _Op > bool operator() (_Op &__o, _It __i) β€” functor execution, bestie. that's it, that's the function ✨

πŸ¦‹ Public Attributes

  • _It _M_finish_iterator β€” the iterator on the last element processed, and yeah it's needed for some algorithms (e. g. std::transform()). lowkey important 🫢

πŸ‘‘ Detailed Description πŸ‘‘

so the whole struct is declared like this:

template<typename _It>
    struct __gnu_parallel::__transform1_selector< _It >

and the description is literally just: "std::transform() __selector, one input sequence variant." β€” short, sweet, iconic. periodt πŸ’–

template<typename _It > template<typename _Op > bool __gnu_parallel::__transform1_selector< _It >::operator() (_Op & __o, _It __i) [inline]

okay so this one is functor execution, and it's [inline], which is a whole mood. here's the tea on the parameters:

  • __o β€” the operator.
  • __i β€” iterator referencing object.

that's the entire deal. no notes πŸ’…


🌈 Member Data Documentation 🌈

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

this one's inherited (yes, from the parent, we love a legacy πŸ’œ). it's the _Iterator on last element processed β€” and it's needed for some algorithms (e. g. std::transform()). don't sleep on it, fr fr. ⭐

ngl the whole page is basically "it's the std::transform() selector, one input sequence variant" said in like four different fonts. iconic behaviour, honestly.

okay bestie that's the page!! it came from libst__gnu_parallel:...selector< _It >(3cxx) at the very bottom, which is the manual label, and the whole thing is courtesy of libstdc++ β€” go drink some water and go slay your parallel algorithms πŸ’–πŸŽ€πŸ¦‹πŸŒΈπŸ«Άβœ¨
