Periodic Alarms 17
The periodic alarm service sends messages to your application at a specied time.
This can be used, for example, by an email client application to periodically log on
to a server to check for incoming messages.
The interface to the periodic alarm service is the system-supplied
protoPeriodicAlarmEditor, shown in Figure 17-3. You can create views
from this proto to allow the user of your application to schedule periodic alarms.
When the alarm times scheduled in this view come up, a message is sent to your
application.
