          <code>Vector</code> is of type <code>Integer</code>. If it is not
          <code>null</code>, it means that the delete list of this operator
          is a variable, and the value of the <code>Integer</code> shows

          <code>Vector</code> is of type <code>Integer</code>. If it is not
          <code>null</code>, it means that the add list of this operator
          is a variable, and the value of the <code>Integer</code> shows
