💖 NAME 💖

bestie, meet __gnu_parallel::_LoserTreePointerUnguarded< __stable, _Tp, _Compare > — she's the stable, unguarded _LoserTree variant that stores pointers. yep that's the whole vibe ✨

this page lives in the Library Functions Manual, and it's all about this one class. iykyk 🫶

🌸 SYNOPSIS 🌸

#include <losertree.h>

okay so first thing, she inherits from:

__gnu_parallel::_LoserTreePointerUnguardedBase< _Tp, _Compare >

like that's her whole ancestry, no cap 💅

🎀 Public Member Functions 🎀

  • _LoserTreePointerUnguarded — the constructor, and her signature is (unsigned int __k, const _Tp &__sentinel, _Compare __comp=std::less< _Tp >()). note that default __comp, it's giving generous 💖
  • void __delete_min_insert (const _Tp &__key, bool __sup) — deletes the min and inserts, exactly as advertised ✨
  • int __get_min_source () — hands you the source of the minimum. iconic 🔥
  • void __init () — sets everything up. the pre-game ritual fr fr 🌸
  • unsigned int __init_winner (unsigned int __root) — figures out the winner starting from __root, and gives you back an unsigned int 👑
  • void __insert_start (const _Tp &__key, int __source, bool) — inserts a starting element. yes the last param is just bool, untyped and mysterious, we love that for her 💀

🦋 Protected Attributes 🦋

  • unsigned int _M_ik — protected, so hands off unless you're family 🫶
  • unsigned int _M_offset — also protected, also an unsigned int, also minding her own business ✨

🌈 Detailed Description 🌈

so the template declaration is literally this, character for character, don't come for me:

template<bool __stable, typename _Tp, typename _Compare>
class __gnu_parallel::_LoserTreePointerUnguarded< __stable, _Tp, _Compare >
"Stable unguarded _LoserTree variant storing pointers.

and the tea ☕ — the unstable variant is implemented below using partial specialization. so if you were looking for the unstable one, she's a different girl, scroll down bestie 😭

👑 Author 👑

Generated automatically by Doxygen for libstdc++ from the source code. not me getting a whole manpage written by a robot and it still ate 💅

mwah that's the whole page! this little masterpiece shipped with libstdc++, and the footer of the original said the same thing the header did — __gnu_para... _Compare >(3), truncated title and all 🎀 go forth and pointer-store your loser trees, bestie, you're the main character now ⭐🦋
