__GNU_PBDS::LU_COUNTER_POLICY(3cxx)

💖 NAME 💖

okay so bestie, we're in the 3cxx manual, and the page header is the extremely truncated __gnu_pbds::lu_...Count, _Alloc >(3cxx) — it literally prints that same truncated title twice, no cap 😭. The actual main character is __gnu_pbds::lu_counter_policy< Max_Count, _Alloc >.

✨ SYNOPSIS ✨

#include <list_update_policy.hpp>

Inherits __gnu_pbds::detail::lu_counter_policy_base< _Alloc::size_type >.

🌸 Public Types 🌸

• enum { max_count }
• typedef _Alloc allocator_type
• typedef detail::rebind_traits< _Alloc, metadata_type >::reference metadata_reference — the reference type for the metadata this functor operates on.
• typedef detail::lu_counter_metadata< size_type > metadata_type — the metadata type this functor operates on.
• typedef allocator_type::size_type size_type

🫶 Public Member Functions 🫶

• metadata_type operator() () const — creates a metadata object.
• bool operator() (metadata_reference r_data) const — decides whether a metadata object should be moved to the front of the list.

🙈 Private Member Functions 🙈

• bool operator() (Metadata_Reference r_data, size_type m_max_count) const
• lu_counter_metadata< size_type > operator() (size_type max_size) const

👑 Detailed Description 👑

template<std::size_t Max_Count = 5, typename _Alloc = std::allocator<char>>
class __gnu_pbds::lu_counter_policy< Max_Count, _Alloc >

The class describes itself as: “A list-update policy that moves elements to the front of the list based on the counter algorithm.”

🎀 Member Typedef Documentation 🎀

template<std::size_t Max_Count = 5, typename _Alloc  = std::allocator<char>>

• typedef detail::rebind_traits<_Alloc,metadata_type>::reference __gnu_pbds::lu_counter_policy< Max_Count, _Alloc >::metadata_reference — the reference type pointing at the metadata this functor operates on.
• typedef detail::lu_counter_metadata<size_type> __gnu_pbds::lu_counter_policy< Max_Count, _Alloc >::metadata_type — the metadata type this functor operates on.

⭐ Member Enumeration Documentation ⭐

template<std::size_t Max_Count = 5, typename _Alloc  = std::allocator<char>>
anonymous enum

• max_count — when some element gets accessed this number of times, it will be moved to the front of the list.

💅 operator() () const

template<std::size_t Max_Count = 5, typename _Alloc  = std::allocator<char>>
metadata_type __gnu_pbds::lu_counter_policy< Max_Count, _Alloc >::operator() () const [inline]

Creates a metadata object.

💅 operator() (metadata_reference r_data) const

template<std::size_t Max_Count = 5, typename _Alloc  = std::allocator<char>>
bool __gnu_pbds::lu_counter_policy< Max_Count, _Alloc >::operator() (metadata_reference r_data) const [inline]

Decides whether a metadata object should be moved to the front of the list.

and that's the sign-off, bestie 🫶 the footer is the truncated libst__gnu_pbds::lu_...Count, _Alloc >(3cxx) line. Source/version is libstdc++, generated from the source code, and there's no date printed on the footer — so I'm not inventing one 😭. Byeeee 🦋
