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