Detailed Description

template<class _Key, class _Tp, class _Hash = hash<_Key>, class _Pred = std::equal_to<_Key>, class _Alloc = std::allocator<std::pair<const _Key, _Tp> >>
class std::unordered_map< _Key, _Tp, _Hash, _Pred, _Alloc >

A standard container composed of unique keys (containing at most one of each key value) that associates values of another type with the keys.

Template Parameters:

_Key	Type of key objects.
_Tp	Type of mapped objects.
_Hash	Hashing function object type, defaults to hash<_Value>.
_Pred	Predicate function object type, defaults to equal_to<_Value>.
_Alloc	Allocator type, defaults to allocator<_Key>.

Meets the requirements of a container, and unordered associative container

The resulting value type of the container is std::pair<const _Key, _Tp>.

Base is _Hashtable, dispatched at compile time via template alias __umap_hashtable.
