template< class... Args >
iterator emplace( const_iterator pos, Args&&... args );
(dal C++11)
Inserisce un nuovo elemento nel contenitore direttamente prima pos. L'elemento è costruito sul posto, cioè non copia o operazioni di spostamento vengono eseguite. Il costruttore dell'elemento viene chiamato con il std::forward<Args>(args)... argomenti. Il tipo di elemento deve essere EmplaceConstructible.
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.
