Method Detail

getStartTime

public Date getStartTime()

Get the time at which the SimpleTrigger should occur.

Specified by:
getStartTime in interface Trigger
Specified by:
getStartTime in class AbstractTrigger<SimpleTrigger>

setStartTime

public void setStartTime(Date startTime)

Set the time at which the SimpleTrigger should occur.

Specified by:
setStartTime in interface org.quartz.spi.MutableTrigger
Specified by:
setStartTime in class AbstractTrigger<SimpleTrigger>
Throws:
IllegalArgumentException - if startTime is null.

getEndTime

public Date getEndTime()

Get the time at which the SimpleTrigger should quit repeating - even if repeastCount isn't yet satisfied.

Specified by:
getEndTime in interface Trigger
Specified by:
getEndTime in class AbstractTrigger<SimpleTrigger>
See Also:
getFinalFireTime()

setEndTime

public void setEndTime(Date endTime)

Set the time at which the SimpleTrigger should quit repeating (and be automatically deleted).

Specified by:
setEndTime in interface org.quartz.spi.MutableTrigger
Specified by:
setEndTime in class AbstractTrigger<SimpleTrigger>
Throws:
IllegalArgumentException - if endTime is before start time.
See Also:
TriggerUtils#computeEndTimeToAllowParticularNumberOfFirings(AbstractTrigger, Calendar, int)

getRepeatCount

public int getRepeatCount()
Description copied from interface: SimpleTrigger

Get the the number of times the SimpleTrigger should repeat, after which it will be automatically deleted.

Specified by:
getRepeatCount in interface SimpleTrigger
See Also:
SimpleTrigger.REPEAT_INDEFINITELY

setRepeatCount

public void setRepeatCount(int repeatCount)

Set the the number of time the SimpleTrigger should repeat, after which it will be automatically deleted.

Throws:
IllegalArgumentException - if repeatCount is < 0
See Also:
SimpleTrigger.REPEAT_INDEFINITELY

getRepeatInterval

public long getRepeatInterval()
Description copied from interface: SimpleTrigger

Get the the time interval (in milliseconds) at which the SimpleTrigger should repeat.

Specified by:
getRepeatInterval in interface SimpleTrigger

setRepeatInterval

public void setRepeatInterval(long repeatInterval)

Set the the time interval (in milliseconds) at which the SimpleTrigger should repeat.

Throws:
IllegalArgumentException - if repeatInterval is <= 0

getTimesTriggered

public int getTimesTriggered()

Get the number of times the SimpleTrigger has already fired.

Specified by:
getTimesTriggered in interface SimpleTrigger

setTimesTriggered

public void setTimesTriggered(int timesTriggered)

Set the number of times the SimpleTrigger has already fired.

validateMisfireInstruction

protected boolean validateMisfireInstruction(int misfireInstruction)
Specified by:
validateMisfireInstruction in class AbstractTrigger<SimpleTrigger>

updateAfterMisfire

public void updateAfterMisfire(Calendar cal)

Updates the SimpleTrigger's state based on the MISFIRE_INSTRUCTION_XXX that was selected when the SimpleTrigger was created.

If the misfire instruction is set to MISFIRE_INSTRUCTION_SMART_POLICY, then the following scheme will be used:

  • If the Repeat Count is 0, then the instruction will be interpreted as MISFIRE_INSTRUCTION_FIRE_NOW.
  • If the Repeat Count is REPEAT_INDEFINITELY, then the instruction will be interpreted as MISFIRE_INSTRUCTION_RESCHEDULE_NEXT_WITH_REMAINING_COUNT. WARNING: using MISFIRE_INSTRUCTION_RESCHEDULE_NEXT_WITH_REMAINING_COUNT with a trigger that has a non-null end-time may cause the trigger to never fire again if the end-time arrived during the misfire time span.
  • If the Repeat Count is > 0, then the instruction will be interpreted as MISFIRE_INSTRUCTION_RESCHEDULE_NOW_WITH_EXISTING_REPEAT_COUNT.

If the misfire instruction is set to Trigger.MISFIRE_INSTRUCTION_SKIP_TO_NEXT_FIRE_AFTER_CURRENT_DATE then the behavior will be identical to

Specified by:
updateAfterMisfire in interface org.quartz.spi.OperableTrigger
Specified by:
updateAfterMisfire in class AbstractTrigger<SimpleTrigger>

triggered

public void triggered(Calendar calendar)

Called when the Scheduler has decided to 'fire' the trigger (execute the associated Job), in order to give the Trigger a chance to update itself for its next triggering (if any).

Specified by:
triggered in interface org.quartz.spi.OperableTrigger
Specified by:
triggered in class AbstractTrigger<SimpleTrigger>
See Also:
AbstractTrigger.executionComplete(JobExecutionContext, JobExecutionException)

updateWithNewCalendar

public void updateWithNewCalendar(Calendar calendar,
                                  long misfireThreshold)
Description copied from class: AbstractTrigger

This method should not be used by the Quartz client.

To be implemented by the concrete class.

The implementation should update the Trigger's state based on the given new version of the associated Calendar (the state should be updated so that it's next fire time is appropriate given the Calendar's new settings).

Specified by:
updateWithNewCalendar in interface org.quartz.spi.OperableTrigger
Specified by:
updateWithNewCalendar in class AbstractTrigger<SimpleTrigger>
See Also:
org.quartz.Trigger#updateWithNewCalendar(org.quartz.Calendar, long)

computeFirstFireTime

public Date computeFirstFireTime(Calendar calendar)

Called by the scheduler at the time a Trigger is first added to the scheduler, in order to have the Trigger compute its first fire time, based on any associated calendar.

After this method has been called, getNextFireTime() should return a valid answer.

Specified by:
computeFirstFireTime in interface org.quartz.spi.OperableTrigger
Specified by:
computeFirstFireTime in class AbstractTrigger<SimpleTrigger>
Returns:
the first time at which the Trigger will be fired by the scheduler, which is also the same value getNextFireTime() will return (until after the first firing of the Trigger).

getNextFireTime

public Date getNextFireTime()

Returns the next time at which the Trigger is scheduled to fire. If the trigger will not fire again, null will be returned. Note that the time returned can possibly be in the past, if the time that was computed for the trigger to next fire has already arrived, but the scheduler has not yet been able to fire the trigger (which would likely be due to lack of resources e.g. threads).

The value returned is not guaranteed to be valid until after the Trigger has been added to the scheduler.

Specified by:
getNextFireTime in interface Trigger
Specified by:
getNextFireTime in class AbstractTrigger<SimpleTrigger>
See Also:
TriggerUtils#computeFireTimesBetween(Trigger, Calendar, Date, Date)

getPreviousFireTime in interface Trigger
Specified by:
getPreviousFireTime in class AbstractTrigger<SimpleTrigger>

setNextFireTime

public void setNextFireTime(Date nextFireTime)

Set the next time at which the SimpleTrigger should fire.

This method should not be invoked by client code.

Specified by:
setNextFireTime in interface org.quartz.spi.OperableTrigger

setPreviousFireTime

public void setPreviousFireTime(Date previousFireTime)

Set the previous time at which the SimpleTrigger fired.

This method should not be invoked by client code.

Specified by:
setPreviousFireTime in interface org.quartz.spi.OperableTrigger

getFireTimeAfter

public Date getFireTimeAfter(Date afterTime)

Returns the next time at which the SimpleTrigger will fire, after the given time. If the trigger will not fire after the given time, null will be returned.

getFireTimeAfter in interface Trigger
Specified by:
getFireTimeAfter in class AbstractTrigger<SimpleTrigger>

getFireTimeBefore

Returns the last time at which the SimpleTrigger will fire, before the given time. If the trigger will not fire before the given time, null will be returned.

computeNumTimesFiredBetween

public int computeNumTimesFiredBetween(Date start,
                                       Date end)

getFinalFireTime

public Date getFinalFireTime()

Returns the final time at which the SimpleTrigger will fire, if repeatCount is REPEAT_INDEFINITELY, null will be returned.

Note that the return time may be in the past.

Specified by:
getFinalFireTime in interface Trigger
Specified by:
getFinalFireTime in class AbstractTrigger<SimpleTrigger>

mayFireAgain

public boolean mayFireAgain()

Determines whether or not the SimpleTrigger will occur again.

SchedulerException

hasAdditionalProperties

public boolean hasAdditionalProperties()
Used by extensions of SimpleTrigger to imply that there are additional properties, specifically so that extensions can choose whether to be stored as a serialized blob, or as a flattened SimpleTrigger table.

Specified by:
hasAdditionalProperties in interface CoreTrigger

public ScheduleBuilder<SimpleTrigger> getScheduleBuilder()
Get a ScheduleBuilder that is configured to produce a schedule identical to this trigger's schedule.
