STD::_NODE_HANDLE(3cxx)

💖 NAME 💖

Okay bestie, this is the 3cxx manual page for std::_Node_handle< _Key, _Value, _NodeAlloc > — literally the node handle type for maps. The top header is the truncated std::_Node_han...e, _NodeAlloc >(3cxx), so if that’s what you saw, you’re in the right place. Periodt. ✨

✨ SYNOPSIS ✨

#include <set>

Inherits std::_Node_handle_common< _Value, _NodeAlloc >. That’s the family tree, no cap. 🫶

🎀 Public Types 🎀

• using allocator_type = __alloc_rebind< _NodeAlloc, _Value > — allocator type, rebinding _NodeAlloc to _Value.
• using key_type = _Key — key type is _Key, simple as that.
• using mapped_type = typename _Value::second_type — mapped type comes from _Value::second_type.

💅 Public Member Functions 💅

• _Node_handle (_Node_handle &&) noexcept=default — move constructor, defaulted and noexcept.
• bool empty () const noexcept — returns bool, const noexcept.
• allocator_type get_allocator () const noexcept — returns allocator_type, const noexcept.
• key_type & key () const noexcept — returns key_type &, const noexcept.
• mapped_type & mapped () const noexcept — returns mapped_type &, const noexcept.
• operator bool () const noexcept — bool conversion operator, const noexcept.
• _Node_handle & operator= (_Node_handle &&) noexcept=default — move assignment, defaulted and noexcept.
• void swap (_Node_handle &__nh) noexcept — swaps with __nh, noexcept.

🫶 Friends 🫶

• template<typename _Key2 , typename _Value2 , typename _ValueAlloc , typename _ExtractKey , typename _Equal , typename _Hash , typename _RangeHash , typename _Unused , typename _RehashPolicy , typename _Traits > class _Hashtable — friend class _Hashtable.
• template<typename _Key2 , typename _Value2 , typename _KeyOfValue , typename _Compare , typename _ValueAlloc > class _Rb_tree — friend class _Rb_tree.
• void swap (_Node_handle &__x, _Node_handle &__y) noexcept(noexcept(__x.swap(__y))) — friend swap for two _Node_handles.

🔥 Detailed Description 🔥

template<typename _Key, typename _Value, typename _NodeAlloc>
class std::_Node_handle< _Key, _Value, _NodeAlloc >

The description is literally "Node handle type for maps. — stray opening quote and all — and it means exactly what it says: node handle type for maps. That’s the whole vibe. 💀

Okay that’s the page, bestie 🫶💖 The footer line is libstdstd::_Node_han...e, _NodeAlloc >(3cxx); source/version is libstdc++ (Doxygen-generated from the source code), and the provided footer doesn’t show a separate date — so no invented date, periodt. 🌈
