/**
|
|
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>
