#include <bslstl_hashtable.h>

Inheritance diagram for bslstl::HashTable_ImplParameters< KEY_CONFIG, HASHER, COMPARATOR, ALLOCATOR >:

Detailed Description

template<class KEY_CONFIG, class HASHER, class COMPARATOR, class ALLOCATOR>
class bslstl::HashTable_ImplParameters< KEY_CONFIG, HASHER, COMPARATOR, ALLOCATOR >

This class holds all the parameterized parts of a HashTable class, efficiently exploiting the empty base optimization without adding unforeseen namespace associations to the HashTable class itself due to the structural inheritance.

const ALLOCATOR &  allocator 
)
inline

Create a HashTable_ImplParameters object having the same hasher and comparator attributes as the specified original, and providing a BidirectionalNodePool using the specified allocator.

◆ HashTable_ImplParameters() [4/4]

template<class KEY_CONFIG , class HASHER , class COMPARATOR , class ALLOCATOR >
bslstl::HashTable_ImplParameters< KEY_CONFIG, HASHER, COMPARATOR, ALLOCATOR >::HashTable_ImplParameters ( bslmf::MovableRef< HashTable_ImplParameters< KEY_CONFIG, HASHER, COMPARATOR, ALLOCATOR > >  original)
inline

Create a HashTable_ImplParameters object with a copy of the hasher and comparator attributes associated with the specified original parameters object, and adopting all outstanding memory allocations and the allocator associated with original.

Note
Note that original is left in a valid but unspecified state.

Member Function Documentation

◆ comparator()

template<class KEY_CONFIG , class HASHER , class COMPARATOR , class ALLOCATOR >
const HashTable_ImplParameters< KEY_CONFIG, HASHER, COMPARATOR, ALLOCATOR >::BaseComparator & bslstl::HashTable_ImplParameters< KEY_CONFIG, HASHER, COMPARATOR, ALLOCATOR >::comparator ( ) const
inline

Return a reference offering non-modifiable access to the comparator functor owned by this object.

◆ hashCodeForKey()

template<class KEY_CONFIG , class HASHER , class COMPARATOR , class ALLOCATOR >
template<class DEDUCED_KEY >
std::size_t bslstl::HashTable_ImplParameters< KEY_CONFIG, HASHER, COMPARATOR, ALLOCATOR >::hashCodeForKey ( DEDUCED_KEY &  key) const
inline

Return the hash code for the specified key using a copy of the hash functor supplied at construction.

Note
Note that this function is provided as a common way to resolve const_cast issues in the case that the stored hash functor has a function call operator that is not declared as const.

◆ hashCodeForTransparentKey()

template<class LOOKUP_KEY >
bsl::enable_if< BloombergLP::bslmf::IsTransparentPredicate< HASHER, LOOKUP_KEY >::value, std::size_t >::type bslstl::HashTable_ImplParameters< KEY_CONFIG, HASHER, COMPARATOR, ALLOCATOR >::hashCodeForTransparentKey ( const LOOKUP_KEY &  key) const
inline

Return the hash code for the specified key using a copy of the hash functor supplied at construction.

Note
Note that this function is provided as a common way to resolve const_cast issues in the case that the stored hash functor has a function call operator that is not declared as const.
