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.

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.

Definition at line 180 of file hash_policy.hpp.

template<bool External_Load_Access, typename Size_Type > \fB__gnu_pbds::hash_load_check_resize_trigger\fP< External_Load_Access, Size_Type >::\fBhash_load_check_resize_trigger\fP (floatload_min = \fC0.125\fP, floatload_max = \fC0.5\fP)

Default constructor, or constructor taking load_min and load_max load factors between which this policy will keep the actual load.

Definition at line 47 of file hash_policy.hpp.

template<bool External_Load_Access, typename Size_Type > \fBstd::pair\fP< float, float > \fB__gnu_pbds::hash_load_check_resize_trigger\fP< External_Load_Access, Size_Type >::get_loads () const\fC [inline]\fP

Returns a pair of the minimal and maximal loads, respectively.

Definition at line 236 of file hash_policy.hpp.

template<bool External_Load_Access, typename Size_Type > void \fB__gnu_pbds::hash_load_check_resize_trigger\fP< External_Load_Access, Size_Type >::notify_cleared ()\fC [protected]\fP

Notifies the table was cleared.

template<bool External_Load_Access, typename Size_Type > void \fB__gnu_pbds::hash_load_check_resize_trigger\fP< External_Load_Access, Size_Type >::notify_inserted (size_typenum_entries)\fC [inline]\fP, \fC [protected]\fP

Notifies an element was inserted. The total number of entries in the table is num_entries.

Definition at line 109 of file hash_policy.hpp.

template<bool External_Load_Access, typename Size_Type > void \fB__gnu_pbds::hash_load_check_resize_trigger\fP< External_Load_Access, Size_Type >::notify_resized (size_typenew_size)\fC [protected]\fP

Notifies the table was resized as a result of this object's signifying that a resize is needed.

Definition at line 151 of file hash_policy.hpp.

template<bool External_Load_Access, typename Size_Type > void \fB__gnu_pbds::hash_load_check_resize_trigger\fP< External_Load_Access, Size_Type >::set_loads (\fBstd::pair\fP< float, float >load_pair)

Sets the loads through a pair of the minimal and maximal loads, respectively.
