It would be more like this:
schedule &ScheduleInterface
scheduleRoundRobinInstance &ScheduleRoundRobin
......
scheduleRoundRobinInstance &= new(ScheduleRoundRobin)
schedule &= scheduleRoundRobinInstance.ScheduleInterface
.....
schedule &= NULL
DISPOSE(scheduleRoundRobinInstance)
Remember, an Interface is just a "contract" that the documented methods are
available. You still need an instance (the "object" in memory) of the class
that implements those methods.
