Creating an Alarm
You create an alarm with the
AlarmManager.CreateAlarm
method.
In the simplest case, you specify the trigger condition in the
AlarmSpec.expression
property and
the action to perform in the
AlarmSpec.action
property. When
the expression evaluates to
true
, the alarm performs the
action.
Figure 1
shows the
CreateAlarm
method.
