CAMSchedule Class (Compact 2013)

3/26/2014

CAMSchedule Class

This class relieves clocks from the burden of managing the advise requests. A clock can delegate such management to this class, provided that it calls this class's Advise method when the earliest event should be fired.

The application can fetch the time of the earliest event by calling GetNextAdviseTime, or the application can track events by a combination of the times returned by Advise and the event times that the clock adds.
