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.

Definition at line 175 of file hash_policy.hpp.

Member Enumeration Documentation

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

template<bool External_Load_Access, typename Size_Type >

__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

template<bool External_Load_Access, typename Size_Type >

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.

Definition at line 236 of file hash_policy.hpp.

template<bool External_Load_Access, typename Size_Type >

void __gnu_pbds::hash_load_check_resize_trigger< External_Load_Access, Size_Type >::notify_cleared ( )

protected

Notifies the table was cleared.

Definition at line 206 of file hash_policy.hpp.

template<bool External_Load_Access, typename Size_Type >

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.

Definition at line 109 of file hash_policy.hpp.

template<bool External_Load_Access, typename Size_Type >

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.

Definition at line 151 of file hash_policy.hpp.

template<bool External_Load_Access, typename Size_Type >

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.
