refreshClusteredJob

public void refreshClusteredJob(com.atlassian.scheduler.config.JobId jobId)

Preform a one-off refresh of a cluster job that is suspected of changing state.

This may be useful to an implementation that is using external messages to communicate changes to clustered job schedules.

Parameters:

jobId - the jobId of the job whose persisted state may have changed

refreshClusteredJobs

public void refreshClusteredJobs()

Perform the routine maintenance that is necessary to guarantee that this cluster node has up-to-date information concerning all clustered jobs.

If the scheduler has already been shutdown, then this request is ignored.

CaesiumSchedulerConfiguration.refreshClusteredJobsIntervalInMinutes()

executeQueuedJob

protected void executeQueuedJob(QueuedJob job)

Callback from a queue worker to handle a QueuedJob that is now due.

Parameters:

job - the job to be executed

enqueueJob

protected void enqueueJob(com.atlassian.scheduler.config.JobId jobId,
                          @Nullable
                          Date expectedTime)

getPendingJobs

@Internal
public Map<com.atlassian.scheduler.config.JobId,Date> getPendingJobs()

Returns the jobs that are currently in the scheduler's "to-do" list, in a map that is ordered by when they are scheduled to run.

Note that this is not part of the atlassian-scheduler API and has been provided primarily as a debugging and instrumentation tool.

Returns:

a map of the jobs that are currently scheduled to run, ordered by their scheduled run time.

createParameterMapSerializer

protected static com.atlassian.scheduler.core.util.ParameterMapSerializer createParameterMapSerializer(CaesiumSchedulerConfiguration config)

The default factory method used for parameter map serializers.

Parameters:

config - the caesium scheduler configuration

Returns:

the newly created parameter map serializer
