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.

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

◆ hash_load_check_resize_trigger()
template<bool External_Load_Access = false, typename Size_Type = std::size_t>
| __gnu_pbds::hash_load_check_resize_trigger< External_Load_Access, 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.
◆ get_loads()
template<bool External_Load_Access = false, typename Size_Type = std::size_t>
Returns a pair of the minimal and maximal loads, respectively.
◆ notify_cleared()
template<bool External_Load_Access = false, typename Size_Type = std::size_t>
Notifies the table was cleared.
◆ notify_inserted()
template<bool External_Load_Access = false, typename Size_Type = std::size_t>
Notifies an element was inserted. The total number of entries in the table is num_entries.
◆ notify_resized()
template<bool External_Load_Access = false, typename Size_Type = std::size_t>
Notifies the table was resized as a result of this object's signifying that a resize is needed.
◆ set_loads()
Sets the loads through a pair of the minimal and maximal loads, respectively.
