Interface CalendarIntervalTrigger

All Known Implementing Classes:

CalendarIntervalTriggerImpl

public interface CalendarIntervalTrigger
extends Trigger

A concrete Trigger that is used to fire a JobDetail based upon repeating calendar time intervals.

The trigger will fire every N (see #setRepeatInterval(int) ) units of calendar time (see #setRepeatIntervalUnit(IntervalUnit)) as specified in the trigger's definition. This trigger can achieve schedules that are not possible with SimpleTrigger (e.g because months are not a fixed number of seconds) or CronTrigger (e.g. because "every 5 months" is not an even divisor of 12).

If you use an interval unit of MONTH then care should be taken when setting a startTime value that is on a day near the end of the month. For example, if you choose a start time that occurs on January 31st, and have a trigger with unit MONTH and interval 1, then the next fire time will be February 28th, and the next time after that will be March 28th - and essentially each subsequent firing will occur on the 28th of the month, even if a 31st day exists. If you want a trigger that always fires on the last day of the month - regardless of the number of days in the month, you should use CronTrigger.

Field Summary

static int	MISFIRE_INSTRUCTION_DO_NOTHING Instructs the Scheduler that upon a mis-fire situation, the CalendarIntervalTrigger wants to have it's next-fire-time updated to the next time in the schedule after the current time (taking into account any associated Calendar, but it does not want to be fired now.
static int	MISFIRE_INSTRUCTION_FIRE_ONCE_NOW Instructs the Scheduler that upon a mis-fire situation, the CalendarIntervalTrigger wants to be fired now by Scheduler.

Method Summary

int	getRepeatInterval() Get the the time interval that will be added to the DateIntervalTrigger's fire time (in the set repeat interval unit) in order to calculate the time of the next trigger repeat.
DateBuilder.IntervalUnit	getRepeatIntervalUnit() Get the interval unit - the time unit on with the interval applies.
int	getTimesTriggered() Get the number of times the DateIntervalTrigger has already fired.
TriggerBuilder<CalendarIntervalTrigger>	getTriggerBuilder() Get a TriggerBuilder that is configured to produce a Trigger identical to this one.
