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

Inserisce un nuovo elemento al contenitore. L'elemento è costruito sul posto, cioè non copia o operazioni di spostamento vengono eseguite. 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)....
