template <class... Args>
iterator emplace_hint( const_iterator hint, Args&&... args );
(depuis C++11)
Insère un nouvel élément dans le récipient, en utilisant hint comme une suggestion où l'élément doit aller. L'élément est réalisé in-situ, c'est à dire pas de copie ou les opérations de déplacement sont effectuées. 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.

[modifier] Complexité

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