RandomRecurrentTriggerExecutor

Runs a RandomRecurrentTrigger: fires a random number of times per day.

The times are random, between startTime and endTime. A daily cron job at startTime sets up the timers for the day. If resumed after startTime, the timers for today are set up right away, unless hasBeenScheduledForToday is true.

A new random number of triggers for a day. Changes on every read.

randomTime

TimeOfDay get randomTime

A new random time between startTime and endTime. Changes on every read.

samplingTimes

List<TimeOfDay> get samplingTimes

Methods

getSchedule

1. @override

List<DateTime> getSchedule(

1. DateTime from,
2. DateTime to, [
3. int max = 100

])

override

Returns the times this trigger fires between from and to.

Ordered by time, except for RandomRecurrentTriggerExecutor.

max limits the number of iterations; its default depends on the implementation.

onResume

1. @override

Future<bool> onResume()

override

Called by resume. Returns true if successfully resumed.

If false, the executor moves to ExecutorState.PausedButShouldBeResumed.
