 \class CaQuery

 \brief This class contains data describing a query used by CaService.

 Thanks to CaQuery object, it's possible to create objects easly

 using this one like CaNotifierFilter for example or define criteria during

 geting entries via service. CaQuery anable set usufull data to do that,

 including entry roles, type names, parent id, sort ordering

 and set on/off flags quickly.

 \example

 \code

 CaQuery query;

 query.setEntryRoles( ItemEntryRole | GroupEntryRole );

 query.setSort( MostUsedSortAttribute, Qt::DescendingOrder );

 query.setFlagsOn( UsedEntryFlag | RemovableEntryFlag | RunningEntryFlag );

 query.setFlagsOff( SystemEntryFlag | VisibleEntryFlag );

 // using CaQuery to get data from DB

 QList<CaEntry *> entries = CaService::instance()->getEntries( query );

 ...

 // using CaQuery to create notifier

 CaQuery queryNot( query );

 CaNotifierFilter notifierFilter( queryNot );

 CaNotifier * notifier = CaService::instance()->createNotifier( notifierFilter );

 ...

 \endcode
