This includes both normal * termination (e.g., due to an application calling the stop() * method) and abnormal termination (e.g., due to some change in the * environment). Examples of abnormal termination include: * *

    *
  • a tuning operation making the service unavailable
  • * *
  • removal of fundamental resources required to present the * service
  • * *
  • withdrawal of CA authorization
  • *
* * PresentationTerminatedEvent is also generated * following a SelectionFailedEvent either if the service * context was not previously in the presenting state or if * recovery of what was being presented previously is not possible. * PresentationTerminatedEvent is only generated when no * components of the requested service can be presented. *

* When a PresentationTerminatedEvent is * generated following a failed selection attempt, the * reason code of the PresentationTerminatedEvent * is derived from the reason code for the * SelectionFailedEvent which preceded it, according * to the table below. *
