Detailed Description

template<class KeyType, class MappedType, class Hasher, template< class > class ExtractHash, class... MappedTypes>
class jmmcg::LIBJMMCG_VER_NAMESPACE::unordered_tuple< KeyType, MappedType, Hasher, ExtractHash, MappedTypes >

A unordered container for a disparate list of types for which the keys form a perfect hash, computable at compile-time.

This class performs zero memory allocations. All of the data is maintained on the stack at the cost of some additional space. There is padding added between each instance of a MappedType to ensure that those instances avoid false sharing in any cache level.

inlinenoexcept

If the construction of any instance of a mapped_type fails, then any already constructed instance of a mapped_type will be correctly deleted, and that failing exception re-thrown. Each of the MappedTypes is either default constructed or constructed with exactly, successively, one of the {arg, args...} parameters passed to this ctor. Thus there must be the same number of MappedTypes as the number of ctor arguments passed in. i.e. sizeof...(MappedTypes)==sizeof...(args)+1.

inlineconstexprnoexcept

Find the instance of mapped_type associated with the instance of key_type.

Algorithmic complexity: O(1) Note that great effort has been made to ensure that this is as fast as possible.

Parameters

key	The instance of key_type associated with a mapped_type.

Returns

A reference to the associated instance of mapped_type.
