| overload to handle register events that is sent after the instance has been registered | |
| virtual void | unregister () |
| overload to handle unregistration of instances | |
| virtual bool | on_exit_request () |
| overload to handle the appication exit request, return true if exiting is allowed and false otherwise | |
