Class XmlIcalCompare

java.lang.Object

org.bedework.util.calendar.diff.XmlIcalCompare

public class XmlIcalCompare
extends Object

This class compares 2 components. These components may contain other sub-components, for example alarms. What is produced is a set of updates to generate one from the other.

For this to work, and for updates to be applicable, we need well defined rules determining how we match components. For example, an event is matched if the UID and RECURRENCE-ID matches.

This is a little more difficult for some components which don't have a uid, alarms for example.
