/**
|
|
*
|
|
* This class should be extended any time a scheduled job needs to be
|
|
* implemented to be executed using
|
|
* {@link org.alfresco.repo.lock.JobLockService JobLockService}. It makes the
|
|
* cluster aware locking of the job transparent to the implementation. On the
|
|
* job's spring {@link org.quartz.JobExecutionContext JobExecutionContext} it
|
|
* will still always have to be passed as parameter the
|
|
* {@link org.alfresco.repo.lock.JobLockService jobLockService}. The name to be
|
|
* used for locking of the job is optional, if none is passed a name will be
|
|
* composed using the simple name of the implementation class. In general if it
|
|
* may make sense to have more than one job setup using the same class you
|
|
* should always use a different name on each
|
|
* {@link org.quartz.JobExecutionContext JobExecutionContext} to differentiate
|
|
* the jobs, unless you want the lock to be shared between the different instances.
|
|
* <p/>
|
|
* The only method to be implemented when extending this class is {@link #executeJob(JobExecutionContext)}.
