__GNU_CXX::HASH_MULTIMAP(3cxx)

💖 NAME 💖

Okay so welcome to the 3cxx manual page for __gnu_cxx::hash_multimap< _Key, _Tp, _HashFn, _EqualKey, _Alloc >. Five template parameters, one class template, zero cap. ✨

✨ SYNOPSIS ✨

Start here, bestie:

#include <hash_map>

🎀 Public Types 🎀

The typedef guest list, exactly as written — no renames, no merges, no skipped entries:

• typedef _Ht::allocator_type allocator_type
• typedef _Ht::const_iterator const_iterator
• typedef _Ht::const_pointer const_pointer
• typedef _Ht::const_reference const_reference
• typedef _Tp data_type
• typedef _Ht::difference_type difference_type
• typedef _Ht::hasher hasher
• typedef _Ht::iterator iterator
• typedef _Ht::key_equal key_equal
• typedef _Ht::key_type key_type
• typedef _Tp mapped_type
• typedef _Ht::pointer pointer
• typedef _Ht::reference reference
• typedef _Ht::size_type size_type
• typedef _Ht::value_type value_type

🦋 Public Member Functions 🦋

Every single one is invited to the function party — constructors first, then the rest, in the exact order from the page:

• template<class _InputIterator > hash_multimap (_InputIterator __f, _InputIterator __l)
• template<class _InputIterator > hash_multimap (_InputIterator __f, _InputIterator __l, size_type __n)
• template<class _InputIterator > hash_multimap (_InputIterator __f, _InputIterator __l, size_type __n, const hasher &__hf)
• template<class _InputIterator > hash_multimap (_InputIterator __f, _InputIterator __l, size_type __n, const hasher &__hf, const key_equal &__eql, const allocator_type &__a=allocator_type())
• hash_multimap (size_type __n)
• hash_multimap (size_type __n, const hasher &__hf)
• hash_multimap (size_type __n, const hasher &__hf, const key_equal &__eql, const allocator_type &__a=allocator_type())
• iterator begin ()
• const_iterator begin () const
• size_type bucket_count () const
• void clear ()
• size_type count (const key_type &__key) const
• size_type elems_in_bucket (size_type __n) const
• bool empty () const
• iterator end ()
• const_iterator end () const
• pair< iterator, iterator > equal_range (const key_type &__key)
• pair< const_iterator, const_iterator > equal_range (const key_type &__key) const
• size_type erase (const key_type &__key)
• void erase (iterator __f, iterator __l)
• void erase (iterator __it)
• iterator find (const key_type &__key)
• const_iterator find (const key_type &__key) const
• allocator_type get_allocator () const
• hasher hash_funct () const
• template<class _InputIterator > void insert (_InputIterator __f, _InputIterator __l)
• iterator insert (const value_type &__obj)
• iterator insert_noresize (const value_type &__obj)
• key_equal key_eq () const
• size_type max_bucket_count () const
• size_type max_size () const
• void resize (size_type __hint)
• size_type size () const
• void swap (hash_multimap &__hs)

🌈 Friends 🌈

Only one friend in this squad, and yes, the template params are written with those exact spaces:

• template<class _K1 , class _T1 , class _HF , class _EqK , class _Al > bool operator== (const hash_multimap< _K1, _T1, _HF, _EqK, _Al > &, const hash_multimap< _K1, _T1, _HF, _EqK, _Al > &)

💅 Detailed Description 💅

Here’s the class template signature with every default kept exactly where it belongs:

template<class _Key, class _Tp, class _HashFn = hash<_Key>, class _EqualKey = equal_to<_Key>, class _Alloc = allocator<_Tp>>
class __gnu_cxx::hash_multimap< _Key, _Tp, _HashFn, _EqualKey, _Alloc >"This is an SGI extension.

And yes, the description literally says: This is an SGI extension. 🫶
