__GNU_CXX::UNARY_COMPOSE(3)

✨ NAME ✨

__gnu_cxx::unary_compose< _Operation1, _Operation2 > — bestie, it's an SGI extension. 💅

---

🌸 SYNOPSIS 🌸

#include <functional>

Inherits from std::unary_function< _Operation2::argument_type, _Operation1::result_type >. yup, it's giving inheritance realness.

Public Types

• typedef _Operation2::argument_type argument_type — argument_type is the type of the argument 🫶
• typedef _Operation1::result_type result_type — result_type is the return type ⭐

Public Member Functions

• unary_compose (const _Operation1 &__x, const _Operation2 &__y)
• _Operation1::result_type operator() (const typename _Operation2::argument_type &__x) const

Protected Attributes

• _Operation1 _M_fn1
• _Operation2 _M_fn2

okay so these two are protected, meaning they're the ~inner workings~ and not for you to poke at from outside, no cap. 💀

💖 Detailed Description 💖

template<class _Operation1, class _Operation2>
class __gnu_cxx::unary_compose< _Operation1, _Operation2 >

"An SGI extension ." — that's literally what it says, and honestly? iconic. 🌈

🎀 Member Typedef Documentation 🎀

typedef _Operation2::argument_type std::unary_function< _Operation2::argument_type, _Operation1::result_type >::argument_type [inherited]

argument_type is the type of the argument ✨

typedef _Operation1::result_type std::unary_function< _Operation2::argument_type, _Operation1::result_type >::result_type [inherited]

result_type is the return type 💜

both of these are inherited, bestie — they come straight from the std::unary_function base, so you don't have to write them yourself. main character energy fr fr. 👑

and that's a wrap, babe — this page lives in the libstdc++ collection, hanging out in manual section 3 with the rest of the Library Functions Manual crew. slay, go write something cute with it. 🎀💖🌸
