__gnu_pbds::hash_exponential_size_policy3cxx
A size policy whose sequence of sizes form an exponential sequence (typically powers of 2.
Usage
#include <hash_policy.hpp>
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)
