JobStore (Quartz Enterprise Job Scheduler 2.3.1-SNAPSHOT API)

All Known Subinterfaces:

ClusteredJobStore, TerracottaJobStoreExtensions

All Known Implementing Classes:

AbstractTerracottaJobStore, JobStoreCMT, JobStoreSupport, JobStoreTX, PlainTerracottaJobStore, RAMJobStore, TerracottaJobStore
```
public interface JobStore
```
The interface to be implemented by classes that want to provide a Job and Trigger storage mechanism for the QuartzScheduler's use.

Storage of Job s and Trigger s should be keyed on the combination of their name and group for uniqueness.

```
    Resume (un-pause) all triggers - equivalent of calling resumeTriggerGroup(group) on every group.
    If any Trigger missed one or more fire-times, then the Trigger's misfire instruction will be applied.
    
    Throws:
    
    JobPersistenceException

    pauseAll()
  - acquireNextTriggers
```
List<OperableTrigger> acquireNextTriggers(long noLaterThan,
                                          int maxCount,
                                          long timeWindow)
                                   throws JobPersistenceException
```
    Get a handle to the next trigger to be fired, and mark it as 'reserved' by the calling scheduler.
    
    Parameters:
    
    noLaterThan - If > 0, the JobStore should only return a Trigger that will fire no later than the time represented in this value as milliseconds.
    
    Throws:
    
    JobPersistenceException
    
    See Also:
    
    releaseAcquiredTrigger(OperableTrigger)
  - releaseAcquiredTrigger
```
void releaseAcquiredTrigger(OperableTrigger trigger)
```
    Inform the JobStore that the scheduler no longer plans to fire the given Trigger, that it had previously acquired (reserved).
  - triggersFired
```
List<TriggerFiredResult> triggersFired(List<OperableTrigger> triggers)
                                throws JobPersistenceException
```
    Inform the JobStore that the scheduler is now firing the given Trigger (executing its associated Job), that it had previously acquired (reserved).
    
    Returns:
    
    may return null if all the triggers or their calendars no longer exist, or if the trigger was not successfully put into the 'executing' state. Preference is to return an empty list if none of the triggers could be fired.
    
    Throws:
    
    JobPersistenceException
  - triggeredJobComplete
```
void triggeredJobComplete(OperableTrigger trigger,
                          JobDetail jobDetail,
                          Trigger.CompletedExecutionInstruction triggerInstCode)
```
    Inform the JobStore that the scheduler has completed the firing of the given Trigger (and the execution of its associated Job completed, threw an exception, or was vetoed), and that the JobDataMap in the given JobDetail should be updated if the Job is stateful.
  - setInstanceId
```
void setInstanceId(String schedInstId)
```
    Inform the JobStore of the Scheduler instance's Id, prior to initialize being invoked.
    
    Since:
    
    1.7
  - setInstanceName
```
void setInstanceName(String schedName)
```
    Inform the JobStore of the Scheduler instance's name, prior to initialize being invoked.
    
    Since:
    
    1.7
  - setThreadPoolSize
```
void setThreadPoolSize(int poolSize)
```
    Tells the JobStore the pool size used to execute jobs
    
    Parameters:
    
    poolSize - amount of threads allocated for job execution
    
    Since:
    
    2.0
  - getAcquireRetryDelay
```
long getAcquireRetryDelay(int failureCount)
```
    Get the amount of time (in ms) to wait when accessing this job store repeatedly fails. Called by the executor thread(s) when calls to acquireNextTriggers(long, int, long) fail more than once in succession, and the thread thus wants to wait a bit before trying again, to not consume 100% CPU, write huge amounts of errors into logs, etc. in cases like the DB being offline/restarting. The delay returned by implementations should be between 20 and 600000 milliseconds.
    
    Parameters:
    
    failureCount - the number of successive failures seen so far
    
    Returns:
    
    the time (in milliseconds) to wait before trying again
