Method Details

add

public void add(SchedulerListener listener)

onExecutionScheduled

public void onExecutionScheduled(TaskInstanceId taskInstanceId,
 Instant executionTime)

Description copied from interface: SchedulerListener

Execution scheduled either by the SchedulerClient or by a CompletionHandler

Specified by:

onExecutionScheduled in interface SchedulerListener

onExecutionStart

public void onExecutionStart(CurrentlyExecuting currentlyExecuting)

Description copied from interface: SchedulerListener

Execution picked and ExecutionHandler about to run. Will typically run in the same thread as onExecutionComplete

Specified by:

onExecutionStart in interface SchedulerListener

onExecutionComplete

public void onExecutionComplete(ExecutionComplete executionComplete)

Description copied from interface: SchedulerListener

ExecutionHandler done. Will typically run in the same thread as onExecutionStart

Specified by:

onExecutionComplete in interface SchedulerListener

onExecutionDead

public void onExecutionDead(Execution execution)

Description copied from interface: SchedulerListener

Scheduler has detected a dead execution. About to run DeadExecutionHandler.

Specified by:

onExecutionDead in interface SchedulerListener

onExecutionFailedHeartbeat

public void onExecutionFailedHeartbeat(CurrentlyExecuting currentlyExecuting)

Description copied from interface: SchedulerListener

Scheduler failed to update heartbeat-timestamp for execution that it is currently executing. Multiple failures will eventually lead to the execution being declared dead (and its DeadExecutionHandler triggered).

Specified by:

onExecutionFailedHeartbeat in interface SchedulerListener

onSchedulerEvent

public void onSchedulerEvent(SchedulerListener.SchedulerEventType type)

Description copied from interface: SchedulerListener

Internal scheduler event. Primarily intended for testing.

Specified by:

onSchedulerEvent in interface SchedulerListener

onCandidateEvent

public void onCandidateEvent(SchedulerListener.CandidateEventType type)

Description copied from interface: SchedulerListener

Internal scheduler event. Primarily intended for testing.

Specified by:

onCandidateEvent in interface SchedulerListener

fireAndLogErrors

public void fireAndLogErrors(SchedulerListener listener,
 String method,
 Runnable r)
