Detailed Description

template<typename Size_Type = std::size_t>
class __gnu_pbds::hash_exponential_size_policy< Size_Type >

A size policy whose sequence of sizes form an exponential sequence (typically powers of 2.

Constructor & Destructor Documentation

template<typename Size_Type = std::size_t>

__gnu_pbds::hash_exponential_size_policy< Size_Type >::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, ...
