-
- The icalvcal_convert routine calls icalvcal_traverse_objects to do
- its work.s his routine steps through through all of the properties
- and components of a VObject. For each name of a property or a
- component, icalvcal_traverse_objects looks up the name in
- conversion_table[]. This table indicates wether the name is of a
- component or a property, lists a routine to handle conversion, and
- has extra data for the conversion.
-
- The conversion routine will create new iCal components or properties
- and add them to the iCal component structure.
-
- The most common conversion routine is dc_prop. This routine converts
- properties for which the text representation of the vCal component
- is identical the iCal representation.
