Datediff and other queries for QueryByExample now working as exprected. All tests passed successfully 2005-03-20 Stefan Eilers <stefan@eilers-online.net> * #1608 Quickfix for problem with DateDiff on SQL backend. I have to rethink this solution, but due to the short time, this should work. 2005-03-19 Stefan Eilers <stefan@eilers-online.net> * Minor update for sorted(). Now ignoring any category search if "DoNotShowWithCategory" filter is activated. * Fixing uninitialized member variable, caused crash of backend 2005-03-18 Stefan Eilers <stefan@eilers-online.net> * Rewrote generic sorted filter and added filter for "DoNotShowWithCategory", needed by addressbook (other filters need to be added!) 2005-01-16 Stefan Eilers <stefan@eilers-online.net> * Added new OPimEventSortVector class, improved OPimSortVector * OPimAccessBackend now supports generic sorting. 2005-01-03 Stefan Eilers <stefan@eilers-online.net> * Fixing bug in API documentation * Moving hasQuerySettings() and querySettings() to OPimAccessTemplate to be available for all frontends 2004-12-28 Stefan Eilers <stefan@eilers-online.net> * Make improved query by example accessable via frontend * Some API documentation improvement * Cleanup of backend api.. * Fixing bug #1501 2004-11-23 Stefan Eilers <stefan@eilers-online.net> * Implement fast and full featured version of sorted() for addressbook * Implement generic queryByExample for all Addressboook backends. It allows incremental search. * Update of API Documentation 2004-11-18 Holger Freyther <freyther@handhelds.org> * Every Access can give a set of Occurrences for a period or a datetime * QueryByExample, Find, Sort can be generically accessed by OPimBase pointer interface * OPimBackendOccurrence gets split up to OPimOccurrences by OPimTemplateBase * Add safeCast to various OPimRecords * Kill memleak in OPimTodo * Add SortVector implementations for OPimTodo and OPimContact 2004-??-?? The Opie Team <opie@handhelds.org> * Implemented some important modifications to allow to use OPimRecords as it is, without have to cast them. This makes it possible to write applications which handling pim data in a generic manner (see opimconvertion tool) (eilers)
