NAME

__gnu_pbds::hash_exponential_size_policy< Size_Type > - A size policy whose sequence of sizes form an exponential sequence (typically powers of 2.

SYNOPSIS

Inherited by __gnu_pbds::hash_standard_resize_policy< Size_Policy, Trigger_Policy, External_Size_Access, Size_Type >.

Public Types


typedef Size_Type size_type

Public Member Functions


hash_exponential_size_policy (size_type start_size=8, size_type grow_factor=2)
Default constructor, or onstructor taking a start_size, or constructor taking a start size and grow_factor. The policy will use the sequence of sizes start_size, start_size* grow_factor, start_size* grow_factor^2, ... void swap (hash_exponential_size_policy< Size_Type > &other)

Protected Member Functions


size_type get_nearest_larger_size (size_type size) const
size_type get_nearest_smaller_size (size_type size) const
