since v10.0.120

The extension point TicketClosedEventListener is a java interface that can be implemented to perform actions within the novomind iAGENT routing process after a ticket has been closed without being answered.

All required information about the ticket is provided by the TicketClosedEvent parameters, which are passed to the various method calls. If you don't need to distinguish the different close events you can just override the method with the TicketClosedEvent parameter. Otherwise override the methods that suit your needs.
