__GNU_PARALLEL::__BINDER2ND(3cxx)

🌸 NAME 🌸

__gnu_parallel::__binder2nd< _Operation, _FirstArgumentType, _SecondArgumentType, _ResultType > — bestie, it's basically std::binder2nd's spiritually identical twin, except this one makes you spell out the argument types yourself instead of making the compiler do the detective work. No cap. 💅

Okay so real talk, this is from the libstdc++ manual, section 3cxx — that's the C++ library docs, not some random sysadmin thing, iykyk.

✨ SYNOPSIS ✨

#include <base.h>

It inherits from std::unary_function< _FirstArgumentType, _ResultType > — so it's a unary function, periodt. 🫶

🎀 Public Types

• typedef _FirstArgumentType argument_type — the type of the argument. That's it. That's the whole vibe check.
• typedef _ResultType result_type — the return type, aka what you get back after the glow-up. ⭐

💖 Public Member Functions

• __binder2nd (const _Operation &__x, const _SecondArgumentType &__y) — the constructor, takes your operation __x and your frozen second argument __y.
• _ResultType operator() (_FirstArgumentType &__x) — call it with a mutable reference to the first argument. Slay.
• _ResultType operator() (const _FirstArgumentType &__x) const — same energy but const and taking a const reference. Choose your fighter. 🔥

🦋 Protected Attributes

• _Operation _M_op — the operation it's holding onto.
• _SecondArgumentType _M_value — the value that gets baked in as the second argument. Iconic.

👑 Detailed Description

template<typename _Operation, typename _FirstArgumentType, typename _SecondArgumentType, typename _ResultType>
class __gnu_parallel::__binder2nd< _Operation, _FirstArgumentType, _SecondArgumentType, _ResultType >

Literally what it says on the tin: "Similar to std::binder2nd, but giving the argument types explicitly." So instead of the library inferring everything, you hand it the types like the responsible main character you are. 🌈

🧚 Member Typedef Documentation

• typedef _FirstArgumentType std::unary_function< _FirstArgumentType , _ResultType >::argument_type [inherited] — inherited, obviously. And yeah: argument_type is the type of the argument.
• typedef _ResultType std::unary_function< _FirstArgumentType , _ResultType >::result_type [inherited] — also inherited, and result_type is the return type. We been knew. 💀
