      template< class... Args > iterator emplace( const_iterator pos, Args&&... args );
      		 (desde C++11)
      Insere um novo elemento para o recipiente diretamente antes pos. O elemento é construído no local, ou seja, nenhuma cópia ou operações de movimentação são executadas. O construtor do elemento é chamado com o std::forward<Args>(args)... argumentos. O tipo de elemento deve ser 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.

      Parâmetros

      pos -
      iterador antes que o novo elemento será construído
      Original:

      Complexidade

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

      Exceções

      Se uma exceção é lançada (por exemplo, pelo construtor), o contêiner é deixado inalterado, tal como se esta função nunca foi chamado (garantia exceção 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).
