template< class... Args > std::pair<iterator,bool> emplace( Args&&... args );		(desde C++11)

Insere um novo elemento ao recipiente. O elemento é construído no local, ou seja, nenhuma cópia ou operações de movimentação são executadas. The constructor of the element type (value_type, that is, std::pair<const Key, T>) is called with exactly the same arguments as supplied to the function, forwarded with std::forward<Args>(args)....

Original:

Inserts a new element to the container. The element is constructed in-place, i.e. no copy or move operations are performed. The constructor of the element type (value_type, that is, std::pair<const Key, T>) is called with exactly the same arguments as supplied to the function, forwarded with std::forward<Args>(args)....
