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 Public Member Functions 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. void swap (hash_load_check_resize_trigger &other) Protected Member Functions bool is_grow_needed (size_type size, size_type num_entries) const bool is_resize_needed () const void notify_cleared () Notifies the table was cleared. void notify_erase_search_collision () void notify_erase_search_end () void notify_erase_search_start () void notify_erased (size_type num_entries) void notify_externally_resized (size_type new_size) void notify_find_search_collision () void notify_find_search_end () void notify_find_search_start () void notify_insert_search_collision () void notify_insert_search_end () void notify_insert_search_start () void notify_inserted (size_type num_entries) Notifies an element was inserted. The total number of entries in the table is num_entries. void notify_resized (size_type new_size) Notifies the table was resized as a result of this object's signifying that a resize is needed.

It keeps the load factor between some load factors load_min and load_max. Definition at line 175 of file hash_policy.hpp. 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.
