## Class SchedulerAccessor

- java.lang.Object
- - org.springframework.scheduling.quartz.SchedulerAccessor

All Implemented Interfaces:
  Aware, ResourceLoaderAware

Direct Known Subclasses:
  SchedulerAccessorBean, SchedulerFactoryBean

    public abstract class SchedulerAccessor
    extends Object
    implements ResourceLoaderAware

Common base class for accessing a Quartz Scheduler, i.e. for registering jobs, triggers and listeners on a `Scheduler` instance.

For concrete usage, check out the `SchedulerFactoryBean` and `SchedulerAccessorBean` classes.

Compatible with Quartz 1.5+ as well as Quartz 2.0/2.1, as of Spring 3.1.

Since:
  2.5.6

### Field Detail

#### logger

    protected final Log logger

#### resourceLoader

    protected ResourceLoader resourceLoader

### Constructor Detail

#### SchedulerAccessor

    public SchedulerAccessor()

### Method Detail

#### setOverwriteExistingJobs

    public void setOverwriteExistingJobs(boolean overwriteExistingJobs)

Set whether any jobs defined on this SchedulerFactoryBean should overwrite existing job definitions. Default is "false", to not overwrite already registered jobs that have been read in from a persistent job store.

#### setJobSchedulingDataLocation

    public void setJobSchedulingDataLocation(String jobSchedulingDataLocation)

Set the location of a Quartz job definition XML file that follows the "job_scheduling_data_1_5" XSD or better. Can be specified to automatically register jobs that are defined in such a file, possibly in addition to jobs defined directly on this SchedulerFactoryBean.

See Also:
  `XmlSchedulingDataProcessor`

#### setJobSchedulingDataLocations

    public void setJobSchedulingDataLocations(String[] jobSchedulingDataLocations)

Set the locations of Quartz job definition XML files that follow the "job_scheduling_data_1_5" XSD or better. Can be specified to automatically register jobs that are defined in such files, possibly in addition to jobs defined directly on this SchedulerFactoryBean.

See Also:
  `XmlSchedulingDataProcessor`

#### setJobDetails

    public void setJobDetails(JobDetail[] jobDetails)

Register a list of JobDetail objects with the Scheduler that this FactoryBean creates, to be referenced by Triggers.

This is not necessary when a Trigger determines the JobDetail itself: In this case, the JobDetail will be implicitly registered in combination with the Trigger.

See Also:
  `setTriggers(org.quartz.Trigger[])`, `JobDetail`, `JobDetailBean`, `JobDetailAwareTrigger`, `Trigger.setJobName(java.lang.String)`

#### setCalendars

    public void setCalendars(Map<String,Calendar> calendars)

Register a list of Quartz Calendar objects with the Scheduler that this FactoryBean creates, to be referenced by Triggers.

Parameters:
  `calendars` - Map with calendar names as keys as Calendar objects as values
See Also:
  `Calendar`, `Trigger.setCalendarName(java.lang.String)`

#### setTriggers

    public void setTriggers(Trigger[] triggers)

Register a list of Trigger objects with the Scheduler that this FactoryBean creates.

If the Trigger determines the corresponding JobDetail itself, the job will be automatically registered with the Scheduler. Else, the respective JobDetail needs to be registered via the "jobDetails" property of this FactoryBean.

See Also:
  `setJobDetails(org.quartz.JobDetail[])`, `JobDetail`, `JobDetailAwareTrigger`, `CronTriggerBean`, `SimpleTriggerBean`

#### setSchedulerListeners

    public void setSchedulerListeners(SchedulerListener[] schedulerListeners)

Specify Quartz SchedulerListeners to be registered with the Scheduler.

#### setGlobalJobListeners

    public void setGlobalJobListeners(JobListener[] globalJobListeners)

Specify global Quartz JobListeners to be registered with the Scheduler. Such JobListeners will apply to all Jobs in the Scheduler.

#### setJobListeners

    public void setJobListeners(JobListener[] jobListeners)

Specify named Quartz JobListeners to be registered with the Scheduler. Such JobListeners will only apply to Jobs that explicitly activate them via their name.

See Also:
  `JobListener.getName()`, `JobDetail.addJobListener(java.lang.String)`, `JobDetailBean.setJobListenerNames(java.lang.String[])`

#### setGlobalTriggerListeners

    public void setGlobalTriggerListeners(TriggerListener[] globalTriggerListeners)

Specify global Quartz TriggerListeners to be registered with the Scheduler. Such TriggerListeners will apply to all Triggers in the Scheduler.

#### setTriggerListeners

    public void setTriggerListeners(TriggerListener[] triggerListeners)

Specify named Quartz TriggerListeners to be registered with the Scheduler. Such TriggerListeners will only apply to Triggers that explicitly activate them via their name.

See Also:
  `TriggerListener.getName()`, `Trigger.addTriggerListener(java.lang.String)`, `CronTriggerBean.setTriggerListenerNames(java.lang.String[])`, `SimpleTriggerBean.setTriggerListenerNames(java.lang.String[])`

#### setTransactionManager

    public void setTransactionManager(PlatformTransactionManager transactionManager)

Set the transaction manager to be used for registering jobs and triggers that are defined by this SchedulerFactoryBean. Default is none; setting this only makes sense when specifying a DataSource for the Scheduler.

#### setResourceLoader

    public void setResourceLoader(ResourceLoader resourceLoader)

Description copied from interface: `ResourceLoaderAware`
Set the ResourceLoader that this object runs in.

This might be a ResourcePatternResolver, which can be checked through `instanceof ResourcePatternResolver`. See also the `ResourcePatternUtils.getResourcePatternResolver` method.

Invoked after population of normal bean properties but before an init callback like InitializingBean's `afterPropertiesSet` or a custom init-method. Invoked before ApplicationContextAware's `setApplicationContext`.

Specified by:
  `setResourceLoader` in interface `ResourceLoaderAware`
Parameters:
  `resourceLoader` - ResourceLoader object to be used by this object
See Also:
  `ResourcePatternResolver`, `ResourcePatternUtils.getResourcePatternResolver(org.springframework.core.io.ResourceLoader)`

#### registerJobsAndTriggers

    protected void registerJobsAndTriggers()
                                    throws SchedulerException

Register jobs and triggers (within a transaction, if possible).

Throws:
  `SchedulerException`

#### registerListeners

    protected void registerListeners()
                              throws SchedulerException

Register all specified listeners with the Scheduler.

Throws:
  `SchedulerException`

#### getScheduler

    protected abstract Scheduler getScheduler()

Template method that determines the Scheduler to operate on. To be implemented by subclasses.
