Public Member Functions
hash_standard_resize_policy ()
Default constructor.
hash_standard_resize_policy (const Size_Policy &r_size_policy)
constructor taking some policies r_size_policy will be copied by the Size_Policy
object of this object.
hash_standard_resize_policy (const Size_Policy &r_size_policy, const Trigger_Policy
&r_trigger_policy)
constructor taking some policies. r_size_policy will be copied by the Size_Policy
object of this object. r_trigger_policy will be copied by the Trigger_Policy object of
this object.
size_type get_actual_size () const
Returns the actual size of the container.
std::pair< float, float > get_loads () const
Returns a pair of the minimal and maximal loads, respectively.
Size_Policy & get_size_policy ()
Access to the Size_Policy object used.
const Size_Policy & get_size_policy () const
Const access to the Size_Policy object used.
Trigger_Policy & get_trigger_policy ()
Access to the Trigger_Policy object used.
const Trigger_Policy & get_trigger_policy () const
Access to the Trigger_Policy object used.
void resize (size_type suggested_new_size)
Resizes the container to suggested_new_size, a suggested size (the actual size will be
determined by the Size_Policy object).
void set_loads (std::pair< float, float > load_pair)
Sets the loads through a pair of the minimal and maximal loads, respectively.

size_type get_nearest_larger_size (size_type size) const
size_type get_nearest_smaller_size (size_type size) const
size_type get_new_size (size_type size, size_type num_used_e) const

current __size of the container is size, and the number of used entries within the
container is num_used_e.

Member Enumeration Documentation
template<bool External_Load_Access = false, typename Size_Type = std::size_t> anonymous enum
[inherited]
Enumerator
external_load_access
Specifies whether the load factor can be accessed externally. The two options have
different trade-offs in terms of flexibility, genericity, and encapsulation.
