template<class... Args> iterator emplace_hint( const_iterator hint, Args&&... args);		(dal C++11)

Inserisce un nuovo elemento al contenitore, utilizzando hint come un suggerimento in cui l'elemento dovrebbe andare. L'elemento è costruito sul posto, cioè non copia o operazioni di spostamento vengono eseguite. The constructor of the element 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, using hint as a suggestion where the element should go. The element is constructed in-place, i.e. no copy or move operations are performed. The constructor of the element is called with exactly the same arguments as supplied to the function, forwarded with std::forward<Args>(args)....

If the insertion failed because the element already exists, returns an iterator to the already existing element with the equivalent key.

Complessità

Logarithmic in the size of the container in general, but amortized constant if the new element is inserted just before hint.
