id of the event object that defines the recurrence criteria for this event object. If an event is recurring (see isRecurring) it represents an occurrence in the series that is started and defined by a specific pattern event. Use the getPatern method in order to obtain the pattern of the current event. A pattern event can be recognized by its recurrenceState field set to the "master" value. The recurrence information defined by the pattern event can be accessed via the recurrencePattern field of the event. If this event is a not member of a recurrence, or is itself a root event, this field will be null.
