The extension point ChatRecategorizedEventListener is a java interface that can be implemented to perform actions within the novomind iAGENT routing process after a chat has been recategorized.

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