org.quartz.listeners.TriggerListenerSupport

All Implemented Interfaces:

TriggerListener

Direct Known Subclasses:

JobInterruptMonitorPlugin

public abstract class TriggerListenerSupport
extends java.lang.Object
implements TriggerListener

A helpful abstract base class for implementors of TriggerListener.

The methods in this class are empty so you only need to override the subset for the TriggerListener events you care about.

You are required to implement TriggerListener.getName() to return the unique name of your TriggerListener.

getLog

protected org.slf4j.Logger getLog()

Get the Logger for this class's category. This should be used by subclasses for logging.

triggerFired

public void triggerFired(Trigger trigger,
                         JobExecutionContext context)

Description copied from interface: TriggerListener

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.

Specified by:

triggerFired in interface TriggerListener

Parameters:

trigger - The Trigger that has fired.

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

vetoJobExecution

public boolean vetoJobExecution(Trigger trigger,
                                JobExecutionContext context)

Description copied from interface: TriggerListener

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.

Specified by:

vetoJobExecution in interface TriggerListener

Parameters:

trigger - The Trigger that has fired.

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

triggerMisfired

public void triggerMisfired(Trigger trigger)

Description copied from interface: TriggerListener

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.

Specified by:

triggerMisfired in interface TriggerListener

Parameters:

trigger - The Trigger that has misfired.

triggerComplete

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

Description copied from interface: TriggerListener

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.

Specified by:

triggerComplete in interface TriggerListener

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.
