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¶
#include <hash_policy.hpp>
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. void swap
(cc_hash_max_collision_check_resize_trigger< External_Load_Access,
Size_Type > &other)

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.
