template< class... Args > iterator emplace( const_iterator pos, Args&&... args );		(начиная с C++11)

Вставляет новый элемент в контейнере непосредственно перед pos. Элемент построен на месте, т.е. не копировать или перемещать операции. Конструктор элемента вызывается с std::forward<Args>(args)... аргументы. Тип элемента должно быть EmplaceConstructible, MoveInsertable and MoveAssignable.

Original:

Inserts a new element into the container directly before pos. The element is constructed in-place, i.e. no copy or move operations are performed. The constructor of the element is called with the arguments std::forward<Args>(args).... The element type must be EmplaceConstructible, MoveInsertable and MoveAssignable.

If the new size() is greater than capacity(), all iterators and references are invalidated. Otherwise, only the iterators and references after the added element are invalidated.

Исключения

Если исключение (например, в конструкторе), контейнер остается без изменений, как если бы эта функция никогда не называли (сильная гарантия исключением).

Original:

If an exception is thrown (e.g. by the constructor), the container is left unmodified, as if this function was never called (strong exception guarantee).
