template <class... Args>
iterator emplace_hint( const_iterator hint, Args&&... args );
(seit C++11)
Fügt ein neues Element in den Behälter mit hint als Anregung, wo das Element gehen sollte. Das Element in-place ist so aufgebaut, dh kein Kopieren oder Verschieben von Operationen durchgeführt werden. 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)....
