| 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 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, 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 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)....The text has been machine-translated via Google Translate.

If rehashing occurs due to the insertion, all iterators are invalidated. Otherwise iterators are not affected. References are not invalidated. Rehashing occurs only if the new number of elements is higher than max_load_factor()*bucket_count().
