__gnu_pbds::lu_move_to_front_policy< _Alloc >(3)      Library Functions Manual

NAME
       __gnu_pbds::lu_move_to_front_policy< _Alloc >

SYNOPSIS
       #include <list_update_policy.hpp>

   Public Types
       typedef _Alloc allocator_type
       typedef detail::rebind_traits< _Alloc, metadata_type >::reference
           metadata_reference
           Reference to metadata on which this functor operates.
       typedef null_type metadata_type
           Metadata on which this functor operates.

   Public Member Functions
       metadata_type operator() () const
           Creates a metadata object.
       bool operator() (metadata_reference r_metadata) const
           Decides whether a metadata object should be moved to the front of
           the list.

Detailed Description
   template<typename _Alloc = std::allocator<char>>
       class __gnu_pbds::lu_move_to_front_policy< _Alloc >"A list-update
       policy that unconditionally moves elements to the front of the list. A
       null type means that each link in a list-based container does not
       actually need metadata.
