All Implemented Interfaces:

BaseEventType, SystemEventType, SystemStatusChangeEventType

public class SystemStatusChangeEvent
extends SystemEvent
implements SystemStatusChangeEventType

A SystemStatusChangeEvent is an Event of SystemStatusChangeEventType that indicates a status change in a system.

For example, if the status indicates an underlying system is not running, then a Client cannot expect any Events from the underlying system. A Server can identify its own status changes using this EventType.
