NAME

__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.

 

SYNOPSIS


 

Public Types


enum { external_load_access }

typedef Size_Type size_type
 

Public Member Functions


cc_hash_max_collision_check_resize_trigger (float load=0.5)
Default constructor, or constructor taking load, a __load factor which it will attempt to maintain.
float get_load () const
Returns the current load.
void set_load (float load)
Sets the load; does not resize the container.

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.
