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¶
#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)
Protected Member Functions¶
