__GNU_CXX::ARRAY_ALLOCATOR_BASE(3cxx)

💖 __gnu_cxx::array_allocator_base< _Tp > — the 3cxx glow-up 💖

okay bestie, sit down, hydrate, and let's talk about __gnu_cxx::array_allocator_base< _Tp >. This is a page from section 3cxx, which is the C++ corner of the manual, and yes it's giving "template meta brain rot" but it's actually so cute when you get it. 🎀

✨ NAME ✨

__gnu_cxx::array_allocator_base< _Tp > — literally just the Base class. that's the whole vibe. it's the foundation, the groundwork, the mother of the family. 💅

---

🌸 SYNOPSIS 🌸

first things first, you gotta pull it in:

#include <array_allocator.h>

and here's the tea: it's Inherited by __gnu_cxx::array_allocator< _Tp, _Array >. so it's not out here doing the main character thing solo, it's the parent, the blueprint, the one who raised them. 🫶

👑 Public Types

these are the little nickname aliases the class hands out, all of them, no skips:

• typedef const _Tp * const_pointer
• typedef const _Tp & const_reference
• typedef ptrdiff_t difference_type
• typedef _Tp * pointer
• typedef _Tp & reference
• typedef size_t size_type
• typedef _Tp value_type

seven of them. iconic. seven little typedef besties. 🦋

💅 Public Member Functions

every single one, in order, exactly as written, because we do NOT leave the girls behind:

• const_pointer address (const_reference __x) const noexcept
• pointer address (reference __x) const noexcept
• template<typename _Up , typename... _Args> void construct (_Up *__p, _Args &&... __args)
• void deallocate (pointer, size_type)
• template<typename _Up > void destroy (_Up *__p)
• size_type max_size () const noexcept

look at those variadic templates. chef's kiss. the ... is doing so much work and never gets credit. 😭

🌈 Detailed Description 🌈

so like, the whole class declaration is:

template<typename _Tp>
    class __gnu_cxx::array_allocator_base< _Tp >

and its entire personality is: Base class. that's it. that's the description. short, sweet, humble, knows its place. queen behavior honestly.

Definition at line 54 of file array_allocator.h.

like, remember that. line 54. it's important later, iykyk. 👑

🎀 Member Typedef Documentation 🎀

here's where every single typedef gets its own little spotlight moment, with its line number so you can go visit it:

• template<typename _Tp > typedef const _Tp* __gnu_cxx::array_allocator_base< _Tp >::const_pointer
  • Definition at line 60 of file array_allocator.h.
• template<typename _Tp > typedef const _Tp& __gnu_cxx::array_allocator_base< _Tp >::const_reference
  • Definition at line 62 of file array_allocator.h.
• template<typename _Tp > typedef ptrdiff_t __gnu_cxx::array_allocator_base< _Tp >::difference_type
  • Definition at line 58 of file array_allocator.h.
• template<typename _Tp > typedef _Tp* __gnu_cxx::array_allocator_base< _Tp >::pointer
  • Definition at line 59 of file array_allocator.h.
• template<typename _Tp > typedef _Tp& __gnu_cxx::array_allocator_base< _Tp >::reference
  • Definition at line 61 of file array_allocator.h.
• template<typename _Tp > typedef size_t __gnu_cxx::array_allocator_base< _Tp >::size_type
  • Definition at line 57 of file array_allocator.h.
• template<typename _Tp > typedef _Tp __gnu_cxx::array_allocator_base< _Tp >::value_type
  • Definition at line 63 of file array_allocator.h.

note the line numbers bouncing around (60, 62, 58, 59, 61, 57, 63) — that's just how the source file is laid out, not me being chaotic. the file is the chaotic one. 🙈

🔥 Member Function Documentation 🔥

now the actual functions, and yes, we're keeping the [inline] and [noexcept] tags because they're part of the fit:

• template<typename _Tp > const_pointer __gnu_cxx::array_allocator_base< _Tp >::address (const_reference __x) const [inline], [noexcept]
  • Definition at line 70 of file array_allocator.h.
• template<typename _Tp > pointer __gnu_cxx::array_allocator_base< _Tp >::address (reference __x) const [inline], [noexcept]
  • Definition at line 66 of file array_allocator.h.
• template<typename _Tp > template<typename _Up , typename... _Args> void __gnu_cxx::array_allocator_base< _Tp >::construct (_Up * __p, _Args &&... __args) [inline]
  • Definition at line 86 of file array_allocator.h.
• template<typename _Tp > void __gnu_cxx::array_allocator_base< _Tp >::deallocate (pointer, size_type) [inline]
  • Definition at line 74 of file array_allocator.h.
• template<typename _Tp > template<typename _Up > void __gnu_cxx::array_allocator_base< _Tp >::destroy (_Up * __p) [inline]
  • Definition at line 91 of file array_allocator.h.
• template<typename _Tp > size_type __gnu_cxx::array_allocator_base< _Tp >::max_size () const [inline], [noexcept]
  • Definition at line 80 of file array_allocator.h.

okay notice how address shows up twice — one for const_reference and one for plain reference, both const, both [inline], both [noexcept]. that's not a typo, that's overload ✨slay✨. and construct and destroy are the template-in-template girlies, they contain multitudes (and typename... _Args). 💀

and that's the whole page!! 🎉 go forth and allocate, or like, don't, since this is the base class and it's just chilling there being foundational. no cap, you understood this, i'm so proud. 🫶🌸

this lil tour was brought to you by libstdc++, section 3cxx — mwah, catch you in the next manpage, bestie!! 💅✨
