## 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.

## 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

inline inherited

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 | 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.
