Method Detail



clone
public Object clone()


Specified by:
clone in interface org.quartz.spi.MutableTrigger
Overrides:
clone in class AbstractTrigger<CronTrigger>







setCronExpression
public void setCronExpression(String cronExpression)
                       throws ParseException





Throws:
ParseException




getCronExpression
public String getCronExpression()


Specified by:
getCronExpression in interface CronTrigger







setCronExpression
public void setCronExpression(CronExpression cronExpression)

Set the CronExpression to the given one.  The TimeZone on the passed-in
 CronExpression over-rides any that was already set on the Trigger.





Parameters:
cronExpression - 




getStartTime
public Date getStartTime()


 Get the time at which the CronTrigger should occur.
 


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







setStartTime
public void setStartTime(Date startTime)

Description copied from class: AbstractTrigger

 The time at which the trigger's scheduling should start.  May or may not
 be the first actual fire time of the trigger, depending upon the type of
 trigger and the settings of the other properties of the trigger.  However
 the first actual first time will not be before this date.
 

 Setting a value in the past may cause a new trigger to compute a first
 fire time that is in the past, which may cause an immediate misfire
 of the trigger.
 


Specified by:
setStartTime in interface org.quartz.spi.MutableTrigger
Specified by:
setStartTime in class AbstractTrigger<CronTrigger>







getEndTime
public Date getEndTime()


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


Specified by:
getEndTime in interface Trigger
Specified by:
getEndTime in class AbstractTrigger<CronTrigger>


See Also:
getFinalFireTime()




setEndTime
public void setEndTime(Date endTime)

Description copied from class: AbstractTrigger

 Set the time at which the Trigger should quit repeating -
 regardless of any remaining repeats (based on the trigger's particular 
 repeat settings). 
 


Specified by:
setEndTime in interface org.quartz.spi.MutableTrigger
Specified by:
setEndTime in class AbstractTrigger<CronTrigger>


See Also:
TriggerUtils#computeEndTimeToAllowParticularNumberOfFirings(AbstractTrigger, Calendar, int)




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<CronTrigger>


See Also:
TriggerUtils#computeFireTimesBetween(Trigger, org.quartz.Calendar , Date, Date)




getPreviousFireTime
public Date getPreviousFireTime()


 Returns the previous time at which the CronTrigger 
 fired. If the trigger has not yet fired, null will be
 returned.


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







setNextFireTime
public void setNextFireTime(Date nextFireTime)


 Sets the next time at which the CronTrigger will 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 CronTrigger fired.
 

This method should not be invoked by client code.



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







getTimeZone
public TimeZone getTimeZone()

Description copied from interface: CronTrigger

 Returns the time zone for which the cronExpression of
 this CronTrigger will be resolved.
 


Specified by:
getTimeZone in interface CronTrigger







setTimeZone
public void setTimeZone(TimeZone timeZone)


 Sets the time zone for which the cronExpression of this
 CronTrigger will be resolved.
 
If setCronExpression(CronExpression) is called after this
 method, the TimeZon setting on the CronExpression will "win".  However
 if setCronExpression(String) is called after this method, the
 time zone applied by this method will remain in effect, since the 
 String cron expression does not carry a time zone!










getFireTimeAfter
public Date getFireTimeAfter(Date afterTime)


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

 Note that the date returned is NOT validated against the related
 org.quartz.Calendar (if any)
 


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







getFinalFireTime
public Date getFinalFireTime()


 NOT YET IMPLEMENTED: Returns the final time at which the 
 CronTrigger will fire.
 

 Note that the return time *may* be in the past. and the date returned is
 not validated against org.quartz.calendar
 


Specified by:

Specified by:
validateMisfireInstruction in class AbstractTrigger<CronTrigger>







updateAfterMisfire
public void updateAfterMisfire(Calendar cal)


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

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


The instruction will be interpreted as MISFIRE_INSTRUCTION_FIRE_ONCE_NOW




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

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

`Date`	`getEndTime()` Get the time at which the `CronTrigger` should quit repeating - even if repeastCount isn't yet satisfied.
`String`	`getExpressionSummary()`
`Date`	`getFinalFireTime()` NOT YET IMPLEMENTED: Returns the final time at which the `CronTrigger` will fire.
`Date`	`getFireTimeAfter(Date afterTime)` Returns the next time at which the `CronTrigger` will fire, after the given time.
`Date`	`getNextFireTime()` Returns the next time at which the `Trigger` is scheduled to fire.
`Date`	`getPreviousFireTime()` Returns the previous time at which the `CronTrigger` fired.
`ScheduleBuilder<CronTrigger>`	`getScheduleBuilder()` Get a `ScheduleBuilder` that is configured to produce a schedule identical to this trigger's schedule.
`Date`	`getStartTime()` Get the time at which the `CronTrigger` should occur.
`protected Date`	`getTimeAfter(Date afterTime)`
`protected Date`	`getTimeBefore(Date endTime)` NOT YET IMPLEMENTED: Returns the time before the given time that this `CronTrigger` will fire.
`TimeZone`	`getTimeZone()` Returns the time zone for which the `cronExpression` of this `CronTrigger` will be resolved.
`boolean`	`hasAdditionalProperties()` Used by extensions of CronTrigger 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 CronTrigger table.
`boolean`	`mayFireAgain()` Determines whether or not the `CronTrigger` will occur again.
`void`	`setCronExpression(CronExpression cronExpression)` Set the CronExpression to the given one.
`void`	`setCronExpression(String cronExpression)`
`void`	`setEndTime(Date endTime)` Set the time at which the `Trigger` should quit repeating - regardless of any remaining repeats (based on the trigger's particular repeat settings).
`void`	`setNextFireTime(Date nextFireTime)` Sets the next time at which the `CronTrigger` will fire.
`void`	`setPreviousFireTime(Date previousFireTime)` Set the previous time at which the `CronTrigger` fired.
`void`	`setStartTime(Date startTime)` The time at which the trigger's scheduling should start.
`void`	`setTimeZone(TimeZone timeZone)` Sets the time zone for which the `cronExpression` of this `CronTrigger` will be resolved.
`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).`
`void`	`updateAfterMisfire(Calendar cal)` Updates the `CronTrigger`'s state based on the MISFIRE_INSTRUCTION_XXX that was selected when the `CronTrigger` was created.
`void`	`updateWithNewCalendar(Calendar calendar, long misfireThreshold)` This method should not be used by the Quartz client.
`protected boolean`	`validateMisfireInstruction(int misfireInstruction)`
`boolean`	`willFireOn(Calendar test)` Determines whether the date and (optionally) time of the given Calendar instance falls on a scheduled fire-time of this trigger.
`boolean`	`willFireOn(Calendar test, boolean dayOnly)` Determines whether the date and (optionally) time of the given Calendar instance falls on a scheduled fire-time of this trigger.
