NAME

__gnu_pbds::hash_load_check_resize_trigger< External_Load_Access, Size_Type > - A resize trigger policy based on a load check. It keeps the load factor between some load factors load_min and load_max.

SYNOPSIS

Inherits __gnu_pbds::detail::hash_load_check_resize_trigger_size_base< Size_Type, External_Load_Access >.

Public Types

enum { external_load_access }

typedef Size_Type size_type

hash_load_check_resize_trigger (float load_min=0.125, float load_max=0.5)
Default constructor, or constructor taking load_min and load_max load factors between which this policy will keep the actual load.
std::pair< float, float > get_loads () const
Returns a pair of the minimal and maximal loads, respectively.
void set_loads (std::pair< float, float > load_pair)
Sets the loads through a pair of the minimal and maximal loads, respectively.

Detailed Description

template<bool External_Load_Access = false, typename Size_Type = std::size_t>

class __gnu_pbds::hash_load_check_resize_trigger< External_Load_Access, Size_Type >" A resize trigger policy based on a load check. It keeps the load factor between some load factors load_min and load_max.

Member Enumeration Documentation

template<bool External_Load_Access = false, typename Size_Type = std::size_t> anonymous enum

Enumerator

external_load_access: Specifies whether the load factor can be accessed externally. The two options have different trade-offs in terms of flexibility, genericity, and encapsulation.
