  31 /**
  32     A wrapper of I18N wrappers. Using this is more expensive than using some
  33     single wrapper classes so use it only if you must pass a single pointer
  34     without knowing in advance what is needed, e.g. for
  35     SfxPoolItem::GetPresentation(). Remember that this wrapper was only created
  36     for convenience to bypass some oddities, if possible don't use it. <p>
  37
  38     Implemented are only the const get...() methods of the wrappers, which are
  39     loaded on demand, for consistency reasons no change of locale is possible.
  40     Only default calendar and default collator are supported. <p>
  41
  42     One exception though is the calendar wrapper: to be able to set a value and
  43     retrieve calendar values it is not const, so methods using this should
  44     reset the calendar to the previous value if it isn't sure where the
  45     IntlWrapper did come from. <p>
