    template< class... Args > iterator emplace( const_iterator pos, Args&&... args );
    		 (seit C++11)
    Fügt ein neues Element in den Behälter direkt vor pos. Das Element in-place ist so aufgebaut, dh kein Kopieren oder Verschieben von Operationen durchgeführt werden. Der Konstruktor des Elements mit den Argumenten std::forward<Args>(args)... genannt. Der Elementtyp muss EmplaceConstructible, MoveInsertable and MoveAssignable sein .
    Original:
