std::__detail::_Equality< _Key, _Value, _Alloc, _ExtractKey, _Equal, _H1, _H2, _Hash, _RehashPolicy, _Traits, _Unique_keys > —

Synopsis

Inherited by std::_Hashtable< _Key, _Tp, _Hash, _Pred, _Alloc >, std::_Hashtable< _Key, _Tp, _Hash, _Pred, std::allocator< std::pair< const _Key, _Tp > > >, and std::_Hashtable< _Value, _Hash, _Pred, _Alloc >.

Detailed Description

template<typename _Key, typename _Value, typename _Alloc, typename _ExtractKey, typename _Equal, typename _H1, typename _H2, typename _Hash, typename _RehashPolicy, typename _Traits, bool _Unique_keys = _Traits::__unique_keys::value>

struct std::__detail::_Equality< _Key, _Value, _Alloc, _ExtractKey, _Equal, _H1, _H2, _Hash, _RehashPolicy, _Traits, _Unique_keys >" Primary class template _Equality.

This is for implementing equality comparison for unordered containers, per N3068, by John Lakos and Pablo Halpern. Algorithmically, we follow closely the reference implementations therein.
