All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`void`	`clear()`
`java.util.List<JobExecution>`	`findJobExecutions(JobInstance jobInstance)`	Return all `JobExecution`s for given `JobInstance`, sorted backwards by creation order (so the first element is the most recent).
`java.util.Set<JobExecution>`	`findRunningJobExecutions(java.lang.String jobName)`
`JobExecution`	`getJobExecution(java.lang.Long executionId)`
`JobExecution`	`getLastJobExecution(JobInstance jobInstance)`	Find the last `JobExecution` to have been created for a given `JobInstance`.
`void`	`saveJobExecution(JobExecution jobExecution)`	Save a new JobExecution.
`void`	`synchronizeStatus(JobExecution jobExecution)`	Because it may be possible that the status of a JobExecution is updated while running, the following method will synchronize only the status and version fields.
`void`	`updateJobExecution(JobExecution jobExecution)`	Update and existing JobExecution.

  - findJobExecutions
```
public java.util.List<JobExecution> findJobExecutions(JobInstance jobInstance)
```
    Description copied from interface: JobExecutionDao
    Return all JobExecutions for given JobInstance, sorted backwards by creation order (so the first element is the most recent).

    Specified by:
    updateJobExecution in interface JobExecutionDao
    Parameters:
    jobExecution - JobExecution instance to be updated.
  - getLastJobExecution
```
public JobExecution getLastJobExecution(@Nullable
                                        JobInstance jobInstance)
```
    Description copied from interface: JobExecutionDao
    Find the last JobExecution to have been created for a given JobInstance.
    Specified by:
    getLastJobExecution in interface JobExecutionDao
    Parameters:
    jobInstance - the JobInstance
    Returns:
    the last JobExecution to execute for this instance or null if no job execution is found for the given job instance.
  - findRunningJobExecutions
```
public java.util.Set<JobExecution> findRunningJobExecutions(java.lang.String jobName)
```
    Specified by:
    findRunningJobExecutions in interface JobExecutionDao
    Parameters:
    jobName - String containing the name of the job.
    Returns:
    all JobExecution that are still running (or indeterminate state), i.e. having null end date, for the specified job name.
  - getJobExecution

@Nullable
public JobExecution getJobExecution(java.lang.Long executionId)
```
    Specified by:
    getJobExecution in interface JobExecutionDao
    Parameters:
    executionId - Long containing the id of the execution.
    Returns:
    the JobExecution for given identifier.
  - synchronizeStatus
```
public void synchronizeStatus(JobExecution jobExecution)
```
    Description copied from interface: JobExecutionDao
    Because it may be possible that the status of a JobExecution is updated while running, the following method will synchronize only the status and version fields.
    Specified by:
    synchronizeStatus in interface JobExecutionDao
