    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, 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.

    All iterators are invalidated. References are invalidated too, unless pos == begin() or pos == end(), in which case they are not invalidated.

    Parametri

    Valore di ritorno

    Iteratore che punta all'elemento in posto.
    Original:
    Iterator pointing to the emplaced element.

    Complessità

    Linear in the lesser of the distances between pos and either of the ends of the container.

    Eccezioni

    Se viene generata un'eccezione (ad esempio dal costruttore), il contenitore viene lasciato invariato, come se questa funzione non è mai stata chiamata (garanzia eccezione forte).
    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).
