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
