Package org.exoplatform.agenda.listener

Class AgendaCalendarLinkCleanupListener

java.lang.Object
org.exoplatform.agenda.listener.AgendaCalendarLinkCleanupListener
All Implemented Interfaces:
org.exoplatform.services.listener.ListenerBase<org.exoplatform.agenda.model.Calendar,Object>
@Component public class AgendaCalendarLinkCleanupListener extends Object implements org.exoplatform.services.listener.ListenerBase<org.exoplatform.agenda.model.Calendar,Object>
Deletes the link of a calendar once the calendar is deleted. Glue only: the deletion is the service's.

The link table carries no foreign key to the calendar table on purpose: a key would make every deletion of a calendar that has a link fail, whichever addon deletes it. A link left behind would open nothing anyway — the feed answers 404 for a calendar that no longer exists — so this listener keeps the table tidy rather than keeping anything safe.
