Detailed Description

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

A resize trigger policy based on collision checks. It keeps the simulated load factor lower than some given load factor.

Definition at line 293 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.

Definition at line 298 of file hash_policy.hpp.
