Public Types¶

enum { max_count }
typedef _Alloc allocator_type
typedef detail::rebind_traits< _Alloc, metadata_type >::reference metadata_reference
Reference to metadata on which this functor operates. typedef detail::lu_counter_metadata< size_type > metadata_type
Metadata on which this functor operates. 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

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

class __gnu_pbds::lu_counter_policy< Max_Count, _Alloc >" A list-update policy that moves elements to the front of the list based on the counter algorithm.

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¶

Reference to metadata on which this functor operates.

template<std::size_t Max_Count = 5, typename _Alloc = std::allocator<char>> typedef detail::lu_counter_metadata<size_type> __gnu_pbds::lu_counter_policy< Max_Count, _Alloc >::metadata_type¶

Metadata on which this functor operates.

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

Enumerator

max_count

When some element is accessed this number of times, it will be moved to the front of the list.

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.

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.
