process

open override fun process(from: Entity, main: Entity, to: Event)

Takes specific data from an event (= event row plus data rows, taken from the content provider) and maps it to the Event data class.

If from references the same object as main, this method is called for a main event (not an exception). If from references another object as main, this method is called for an exception (not a main event).

So you can use (note the referential equality operator):

val isMainEvent = from === main  // or
val isException = from !== main

In a later step of refactoring, it should map to net.fortuna.ical4j.model.component.VEvent.

Parameters

from

event from content provider

main

main event from content provider

to

destination object where the mapped data are stored (no explicit null values needed for fields that are not present)

Throws

InvalidLocalResourceException

on missing or invalid required fields (like android.provider.CalendarContract.Events.DTSTART)
