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

Вставляет новый элемент в контейнере. Элемент построен на месте, т.е. не копировать или перемещать операции. 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)....
