Detailed Description

template<bool External_Load_Access = false, typename Size_Type = std::size_t>
class __gnu_pbds::hash_load_check_resize_trigger< External_Load_Access, Size_Type >

A resize trigger policy based on a load check. It keeps the load factor between some load factors load_min and load_max.

Member Typedef Documentation

◆ size_type

template<bool External_Load_Access = false, typename Size_Type = std::size_t>
typedef Size_Type __gnu_pbds::hash_load_check_resize_trigger< External_Load_Access, Size_Type >::size_type

Definition at line 178 of file hash_policy.hpp.

Member Enumeration Documentation

◆ anonymous enum

template<bool External_Load_Access = false, typename Size_Type = std::size_t>
anonymous enum
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.

Definition at line 180 of file hash_policy.hpp.

Constructor & Destructor Documentation

◆ hash_load_check_resize_trigger()

template<bool External_Load_Access = false, typename Size_Type = std::size_t>
__gnu_pbds::hash_load_check_resize_trigger< External_Load_Access, Size_Type >::hash_load_check_resize_trigger ( float  load_min = 0.125,
float  load_max = 0.5 
)

Default constructor, or constructor taking load_min and load_max load factors between which this policy will keep the actual load.

Member Function Documentation

◆ 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
inline

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

◆ notify_cleared()

template<bool External_Load_Access = false, typename Size_Type = std::size_t>
void __gnu_pbds::hash_load_check_resize_trigger< External_Load_Access, Size_Type >::notify_cleared ( )
protected

Notifies the table was cleared.

◆ notify_inserted()

template<bool External_Load_Access = false, typename Size_Type = std::size_t>
void __gnu_pbds::hash_load_check_resize_trigger< External_Load_Access, Size_Type >::notify_inserted ( size_type  num_entries)
inlineprotected

Notifies an element was inserted. The total number of entries in the table is num_entries.

◆ notify_resized()

template<bool External_Load_Access = false, typename Size_Type = std::size_t>
void __gnu_pbds::hash_load_check_resize_trigger< External_Load_Access, Size_Type >::notify_resized ( size_type  new_size)
protected

Notifies the table was resized as a result of this object's signifying that a resize is needed.

◆ set_loads()

template<bool External_Load_Access = false, typename Size_Type = std::size_t>
void __gnu_pbds::hash_load_check_resize_trigger< External_Load_Access, Size_Type >::set_loads ( std::pair< float, float >  load_pair)

Sets the loads through a pair of the minimal and maximal loads, respectively.
