💖 NAME 💖

__gnu_parallel::_Lexicographic< _T1, _T2, _Compare > — bestie, this thing compares a pair of types lexicographically, ascending. That's it, that's the whole job. 👑

This page lives in the libstdc++ Library Functions Manual, so if you're the kind of girl who reads C++ library docs for fun (me, I'm that girl), welcome home. 🎀

✨ SYNOPSIS ✨

#include <multiseq_selection.h>

Inherits std::binary_function< std::pair< _T1, _T2 >, std::pair< _T1, _T2 >, bool >.

No cap, it really does inherit all of that. It's giving functor with a pedigree. 💅

🌸 Public Types

  • typedef std::pair< _T1, _T2 > first_argument_type — first_argument_type is the type of the first argument.
  • typedef bool result_type — result_type is the return type. (Yes babe, bool. It's a yes/no girlie. 🫶)
  • typedef std::pair< _T1, _T2 > second_argument_type — second_argument_type is the type of the second argument.

🦋 Public Member Functions

  • _Lexicographic (_Compare &__comp) — the constructor, she takes a reference to your comparator and keeps the vibe going.
  • bool operator() (const std::pair< _T1, _T2 > &__p1, const std::pair< _T1, _T2 > &__p2) const — the actual call operator, const and everything. Two pairs walk in, a bool walks out. Iconic behaviour honestly.

💜 Detailed Description 💜

template<typename _T1, typename _T2, typename _Compare>
class __gnu_parallel::_Lexicographic< _T1, _T2, _Compare >

Compare __a pair of types lexicographically, ascending.

Note: that __a is literally how it's written in the source docs, so I'm leaving it exactly as-is. Not me fixing typos in official documentation 💀

So like — three template params (_T1, _T2, _Compare), and the whole personality of this class is "compare two std::pairs and tell me which one comes first." Ascending order, lexicographic rules, periodt. ⭐

🎀 Member Typedef Documentation 🎀

typedef std::pair< _T1, _T2 > std::binary_function< std::pair< _T1, _T2 >, std::pair< _T1, _T2 >, bool >::first_argument_type [inherited]

first_argument_type is the type of the first argument.

typedef bool std::binary_function< std::pair< _T1, _T2 >, std::pair< _T1, _T2 >, bool >::result_type [inherited]

result_type is the return type.

typedef std::pair< _T1, _T2 > std::binary_function< std::pair< _T1, _T2 >, std::pair< _T1, _T2 >, bool >::second_argument_type [inherited]

second_argument_type is the type of the second argument.

Lowkey obsessed with how all three of these are just the base class handing down its little typedefs like family heirlooms. Inherited, every single one. 🧚

🌈 Author 🌈

Generated automatically by Doxygen for libstdc++ from the source code.

Not a human author, bestie — it's the Doxygen machine doing its thing. Don't @ me, I don't write these, I just make them cute. 😭

Okay that's the whole page!! 🎉 Everything you needed, nothing skipped, all facts intact, main character energy fully deployed. This one's a libstdc++ joint, straight out of the Library Functions Manual — go forth and compare your pairs lexicographically, ascending. Mwah. 💖🌸✨
