Interface TriggerListener

All Known Implementing Classes:

BroadcastTriggerListener, JobInterruptMonitorPlugin, LoggingTriggerHistoryPlugin, TriggerListenerSupport

public interface TriggerListener

The interface to be implemented by classes that want to be informed when a Trigger fires. In general, applications that use a Scheduler will not have use for this mechanism.

Method Summary

Modifier and Type	Method and Description
String	getName() Get the name of the TriggerListener.
void	triggerComplete(Trigger trigger, JobExecutionContext context, Trigger.CompletedExecutionInstruction triggerInstructionCode) Called by the Scheduler when a Trigger has fired, it's associated JobDetail has been executed, and it's triggered(xx) method has been called.
void	triggerFired(Trigger trigger, JobExecutionContext context) Called by the Scheduler when a Trigger has fired, and it's associated JobDetail is about to be executed.
void	triggerMisfired(Trigger trigger) Called by the Scheduler when a Trigger has misfired.
boolean	vetoJobExecution(Trigger trigger, JobExecutionContext context) Called by the Scheduler when a Trigger has fired, and it's associated JobDetail is about to be executed.

Method Detail

getName

String getName()

Get the name of the TriggerListener.

triggerFired

void triggerFired(Trigger trigger,
                  JobExecutionContext context)

Called by the Scheduler when a Trigger has fired, and it's associated JobDetail is about to be executed.

It is called before the vetoJobExecution(..) method of this interface.

Parameters:

trigger - The Trigger that has fired.

context - The JobExecutionContext that will be passed to the Job'sexecute(xx) method.

vetoJobExecution

boolean vetoJobExecution(Trigger trigger,
                         JobExecutionContext context)

Called by the Scheduler when a Trigger has fired, and it's associated JobDetail is about to be executed. If the implementation vetos the execution (via returning true), the job's execute method will not be called.

It is called after the triggerFired(..) method of this interface.

Parameters:

trigger - The Trigger that has fired.

context - The JobExecutionContext that will be passed to the Job'sexecute(xx) method.

triggerMisfired

void triggerMisfired(Trigger trigger)

Called by the Scheduler when a Trigger has misfired.

Consideration should be given to how much time is spent in this method, as it will affect all triggers that are misfiring. If you have lots of triggers misfiring at once, it could be an issue it this method does a lot.

Parameters:

trigger - The Trigger that has misfired.

triggerComplete

void triggerComplete(Trigger trigger,
                     JobExecutionContext context,
                     Trigger.CompletedExecutionInstruction triggerInstructionCode)

Called by the Scheduler when a Trigger has fired, it's associated JobDetail has been executed, and it's triggered(xx) method has been called.

Parameters:

trigger - The Trigger that was fired.

context - The JobExecutionContext that was passed to the Job'sexecute(xx) method.

triggerInstructionCode - the result of the call on the Trigger'striggered(xx) method.
