Interface JobDetail

All Superinterfaces:

Cloneable, Serializable

All Known Implementing Classes:

JobDetailImpl

public interface JobDetail
extends Serializable, Cloneable

Conveys the detail properties of a given Job instance. JobDetails are to be created/defined with JobBuilder.

Quartz does not store an actual instance of a Job class, but instead allows you to define an instance of one, through the use of a JobDetail.

Jobs have a name and group associated with them, which should uniquely identify them within a single Scheduler.

Triggers are the 'mechanism' by which Jobs are scheduled. Many Triggers can point to the same Job, but a single Trigger can only point to one Job.

Modifier and Type	Method and Description
Object	clone()
String	getDescription() Return the description given to the Job instance by its creator (if any).
JobBuilder	getJobBuilder() Get a JobBuilder that is configured to produce a JobDetail identical to this one.
Class<? extends Job>	getJobClass() Get the instance of Job that will be executed.
JobDataMap	getJobDataMap() Get the JobDataMap that is associated with the Job.
JobKey	getKey()
boolean	isConcurrentExectionDisallowed()
boolean	isDurable() Whether or not the Job should remain stored after it is orphaned (no Triggers point to it).
boolean	isPersistJobDataAfterExecution()
boolean	requestsRecovery() Instructs the Scheduler whether or not the Job should be re-executed if a 'recovery' or 'fail-over' situation is encountered.

Method Detail

getKey

JobKey getKey()

getDescription

String getDescription()

Return the description given to the Job instance by its creator (if any).

Returns:

null if no description was set.

getJobClass

Class<? extends Job> getJobClass()

Get the instance of Job that will be executed.

getJobDataMap

JobDataMap getJobDataMap()

Get the JobDataMap that is associated with the Job.

isDurable

boolean isDurable()

Whether or not the Job should remain stored after it is orphaned (no Triggers point to it).

If not explicitly set, the default value is false.

Returns:

true if the Job should remain persisted after being orphaned.

isPersistJobDataAfterExecution

boolean isPersistJobDataAfterExecution()

Returns:

whether the associated Job class carries the PersistJobDataAfterExecution annotation.

See Also:

PersistJobDataAfterExecution

isConcurrentExectionDisallowed

boolean isConcurrentExectionDisallowed()

Returns:

whether the associated Job class carries the DisallowConcurrentExecution annotation.

See Also:

DisallowConcurrentExecution

requestsRecovery

boolean requestsRecovery()

Instructs the Scheduler whether or not the Job should be re-executed if a 'recovery' or 'fail-over' situation is encountered.

If not explicitly set, the default value is false.

JobExecutionContext.isRecovering()

clone

Object clone()

getJobBuilder

JobBuilder getJobBuilder()

Get a JobBuilder that is configured to produce a JobDetail identical to this one.
