public class PresentationChangedEvent
extends ServiceContextEvent

PresentationChangedEvent indicates that the content being presented in the ServiceContext has changed. PresentationChangedEvent is the parent class of events indicating dynamic changes to the presentation of a service due to interaction with the CA system. It is generated when neither AlternativeContentEvent nor NormalContentEvent are applicable.

Applications may determine the nature of the new content by querying the current ServiceContentHandler instances of the ServiceContext.
