All Implemented Interfaces:

CalendarHandler

public class EtagsHandler
extends AbstractCalendarHandler

Class which handles the Syncing through the use of Etags. First it sends a Calendar-query, and checks all the etags for events. Then, for each href and etag, we get, something like key-value pair.

We then check for three things:

• Addition of a new event.
• Modification of an existing event.
• Deletion of events which are not in the response.
