Backend Changes:
Each Backend can:
-Sort and Filter a set of Records/AllRecords (which can be filtered again)
-QueryByExample by every Backend
-Occurrences for a period of time and a QDateTime
-More common implementation
-OPimBackendOccurrence with common splitting to OPimOccurrence
Diffstat (limited to 'libopie2/opiepim/backend/obackendfactory.h') (more/less context) (ignore whitespace changes)
