NAME¶
__gnu_pbds::lu_move_to_front_policy< _Alloc >
SYNOPSIS¶
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.
