- Icalset is the "base class" for representations of a collection of
- iCal components. Derived classes (actually delegates) include:
-
- icalfileset Store components in a single file
- icaldirset Store components in multiple files in a directory
- icalheapset Store components on the heap
- icalmysqlset Store components in a mysql database.
