Detailed Description

template<typename Size_Policy = hash_exponential_size_policy<>, typename Trigger_Policy = hash_load_check_resize_trigger<>, bool External_Size_Access = false, typename Size_Type = std::size_t>
class __gnu_pbds::hash_standard_resize_policy< Size_Policy, Trigger_Policy, External_Size_Access, Size_Type >

A resize policy which delegates operations to size and trigger policies.

Member Enumeration Documentation

◆ anonymous enum

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.

__gnu_pbds::hash_standard_resize_policy< Size_Policy, Trigger_Policy, External_Size_Access, Size_Type >::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() [3/3]

template<typename Size_Policy = hash_exponential_size_policy<>, typename Trigger_Policy = hash_load_check_resize_trigger<>, bool External_Size_Access = false, typename Size_Type = std::size_t>

Member Function Documentation

◆ get_actual_size()

template<typename Size_Policy = hash_exponential_size_policy<>, typename Trigger_Policy = hash_load_check_resize_trigger<>, bool External_Size_Access = false, typename Size_Type = std::size_t>
size_type __gnu_pbds::hash_standard_resize_policy< Size_Policy, Trigger_Policy, External_Size_Access, Size_Type >::get_actual_size ( ) const
inline

Returns the actual size of the container.

◆ get_loads()

template<bool External_Load_Access = false, typename Size_Type = std::size_t>
std::pair<float, float> __gnu_pbds::hash_load_check_resize_trigger< External_Load_Access, Size_Type >::get_loads ( ) const
inlineinherited

Returns a pair of the minimal and maximal loads, respectively.

◆ get_new_size()

template<typename Size_Policy = hash_exponential_size_policy<>, typename Trigger_Policy = hash_load_check_resize_trigger<>, bool External_Size_Access = false, typename Size_Type = std::size_t>
size_type __gnu_pbds::hash_standard_resize_policy< Size_Policy, Trigger_Policy, External_Size_Access, Size_Type >::get_new_size ( size_type  size,
size_type  num_used_e 
) const
protected

Queries what the new size should be, when the container is resized naturally. The current __size of the container is size, and the number of used entries within the container is num_used_e.

◆ get_size_policy() [1/2]

template<typename Size_Policy = hash_exponential_size_policy<>, typename Trigger_Policy = hash_load_check_resize_trigger<>, bool External_Size_Access = false, typename Size_Type = std::size_t>
Size_Policy& __gnu_pbds::hash_standard_resize_policy< Size_Policy, Trigger_Policy, External_Size_Access, Size_Type >::get_size_policy ( )

Access to the Size_Policy object used.

◆ get_size_policy() [2/2]

template<typename Size_Policy = hash_exponential_size_policy<>, typename Trigger_Policy = hash_load_check_resize_trigger<>, bool External_Size_Access = false, typename Size_Type = std::size_t>
const Size_Policy& __gnu_pbds::hash_standard_resize_policy< Size_Policy, Trigger_Policy, External_Size_Access, Size_Type >::get_size_policy ( ) const

Const access to the Size_Policy object used.

◆ get_trigger_policy() [1/2]

template<typename Size_Policy = hash_exponential_size_policy<>, typename Trigger_Policy = hash_load_check_resize_trigger<>, bool External_Size_Access = false, typename Size_Type = std::size_t>
Trigger_Policy& __gnu_pbds::hash_standard_resize_policy< Size_Policy, Trigger_Policy, External_Size_Access, Size_Type >::get_trigger_policy ( )

Access to the Trigger_Policy object used.

◆ get_trigger_policy() [2/2]

template<typename Size_Policy = hash_exponential_size_policy<>, typename Trigger_Policy = hash_load_check_resize_trigger<>, bool External_Size_Access = false, typename Size_Type = std::size_t>
const Trigger_Policy& __gnu_pbds::hash_standard_resize_policy< Size_Policy, Trigger_Policy, External_Size_Access, Size_Type >::get_trigger_policy ( ) const

Access to the Trigger_Policy object used.

◆ resize()

template<typename Size_Policy = hash_exponential_size_policy<>, typename Trigger_Policy = hash_load_check_resize_trigger<>, bool External_Size_Access = false, typename Size_Type = std::size_t>
void __gnu_pbds::hash_standard_resize_policy< Size_Policy, Trigger_Policy, External_Size_Access, Size_Type >::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).

◆ set_loads()
