how i ieditableobject.endedit atomic?

if i have an castle category implements ieditableobject, i competence have endedit doing this:

public vacant endedit()
{
    // beginedit have set _editinprogress save *editing fields
    (_editinprogress)
    {
        _line1 = _line1editing;
        _line2 = _line2editing;
        _city = _cityediting;
        _state = _stateediting;
        _postalcode = _postalcodeediting;
        _editinprogress = false;
    }
}

if there an difference _city, following _line1, _line2, presumably _city should revert.
this problem isn't unparalleled endedit nonetheless substantially found places well.
