Constructor Detail

JobExecutionContextImpl

public JobExecutionContextImpl(Scheduler scheduler,
                               org.quartz.spi.TriggerFiredBundle firedBundle,
                               Job job)

Create a JobExcecutionContext with the given context data.

Method Detail

getScheduler

public Scheduler getScheduler()
Description copied from interface: JobExecutionContext

Get a handle to the Scheduler instance that fired the Job.

Specified by:
getScheduler in interface JobExecutionContext

getTrigger

public Trigger getTrigger()
Description copied from interface: JobExecutionContext

Get a handle to the Trigger instance that fired the Job.

Specified by:
getTrigger in interface JobExecutionContext

getCalendar

public Calendar getCalendar()
Description copied from interface: JobExecutionContext

Get a handle to the Calendar referenced by the Trigger instance that fired the Job.

Specified by:
getCalendar in interface JobExecutionContext

isRecovering

public boolean isRecovering()
Description copied from interface: JobExecutionContext

If the Job is being re-executed because of a 'recovery' situation, this method will return true.

Specified by:
isRecovering in interface JobExecutionContext

incrementRefireCount

public void incrementRefireCount()

getRefireCount

public int getRefireCount()
Specified by:
getRefireCount in interface JobExecutionContext

getMergedJobDataMap

public JobDataMap getMergedJobDataMap()
Description copied from interface: JobExecutionContext

Get the convenience JobDataMap of this execution context.

The JobDataMap found on this object serves as a convenience - it is a merge of the JobDataMap found on the JobDetail and the one found on the Trigger, with the value in the latter overriding any same-named values in the former. It is thus considered a 'best practice' that the execute code of a Job retrieve data from the JobDataMap found on this object.

NOTE: Do not expect value 'set' into this JobDataMap to somehow be set back onto a StatefulJob's own JobDataMap.

Attempts to change the contents of this map typically result in an IllegalStateException.

Specified by:
getMergedJobDataMap in interface JobExecutionContext

getJobDetail

public JobDetail getJobDetail()
Description copied from interface: JobExecutionContext

Get the JobDetail associated with the Job.

Specified by:
getJobDetail in interface JobExecutionContext

getJobInstance

public Job getJobInstance()
Description copied from interface: JobExecutionContext

Get the instance of the Job that was created for this execution.

Note: The Job instance is not available through remote scheduler interfaces.

Specified by:
getJobInstance in interface JobExecutionContext

getFireTime

public Date getFireTime()
Description copied from interface: JobExecutionContext
The actual time the trigger fired. For instance the scheduled time may have been 10:00:00 but the actual fire time may have been 10:00:03 if the scheduler was too busy.

Specified by:
getFireTime in interface JobExecutionContext
Returns:
Returns the fireTime.
See Also:
JobExecutionContext.getScheduledFireTime()

getScheduledFireTime

public Date getScheduledFireTime()
Description copied from interface: JobExecutionContext
The scheduled time the trigger fired for. For instance the scheduled time may have been 10:00:00 but the actual fire time may have been 10:00:03 if the scheduler was too busy.

Specified by:
getScheduledFireTime in interface JobExecutionContext
Returns:
Returns the scheduledFireTime.
See Also:
JobExecutionContext.getFireTime()

getPreviousFireTime

public Date getPreviousFireTime()
Specified by:
getPreviousFireTime in interface JobExecutionContext

getNextFireTime

public Date getNextFireTime()
Specified by:
getNextFireTime in interface JobExecutionContext

toString

public String toString()
Overrides:
toString in class Object

getResult

public Object getResult()
Description copied from interface: JobExecutionContext
Returns the result (if any) that the Job set before its execution completed (the type of object set as the result is entirely up to the particular job).

The result itself is meaningless to Quartz, but may be informative to JobListeners or TriggerListeners that are watching the job's execution.

Specified by:
getResult in interface JobExecutionContext
Returns:
Returns the result.

setResult

public void setResult(Object result)
Description copied from interface: JobExecutionContext
Set the result (if any) of the Job's execution (the type of object set as the result is entirely up to the particular job).

The result itself is meaningless to Quartz, but may be informative to JobListeners or TriggerListeners that are watching the job's execution.

Specified by:
setResult in interface JobExecutionContext

getJobRunTime

public long getJobRunTime()
Description copied from interface: JobExecutionContext
The amount of time the job ran for (in milliseconds). The returned value will be -1 until the job has actually completed (or thrown an exception), and is therefore generally only useful to JobListeners and TriggerListeners.

Specified by:
getJobRunTime in interface JobExecutionContext
Returns:
Returns the jobRunTime.

setJobRunTime

public void setJobRunTime(long jobRunTime)
Parameters:
jobRunTime - The jobRunTime to set.

put

public void put(Object key,
                Object value)
Description copied from interface: JobExecutionContext
Put the specified value into the context's data map with the given key. Possibly useful for sharing data between listeners and jobs.

NOTE: this data is volatile - it is lost after the job execution completes, and all TriggerListeners and JobListeners have been notified.

Specified by:
put in interface JobExecutionContext

get

public Object get(Object key)
Description copied from interface: JobExecutionContext
Get the value with the given key from the context's data map.

Specified by:
get in interface JobExecutionContext
