Method Details

runAtFixedRateAsync

public void runAtFixedRateAsync(Duration delay,
 Task task)

Description copied from interface: ProcessingScheduleService

Schedule a task to execute at a fixed rate. After an initial delay, the task is executed. Once the task is executed, it is rescheduled with the same delay again.

The execution of the scheduled task is running asynchronously/concurrently to task scheduled through non-async methods. While other, non-async methods guarantee the execution order of scheduled tasks and always execute scheduled tasks on the same thread, this method does not guarantee this.

Note that time-traveling in tests only affects the delay of the currently scheduled next task and not any of the iterations after. This is because the next task is scheduled with the delay counted from the new time (i.e. the time after time traveling + task execution duration + delay duration = scheduled time of the next task).

Specified by:

runAtFixedRateAsync in interface ProcessingScheduleService

Parameters:

delay - The delay to wait initially and between each run

task - The task to execute at the fixed rate

runDelayedAsync

public SimpleProcessingScheduleService.ScheduledTask runDelayedAsync(Duration delay,
 Task task)

Description copied from interface: ProcessingScheduleService

Schedule a task to execute with a specific delay. After that delay, the task is executed.

The execution of the scheduled task is running asynchronously/concurrently to task scheduled through non-async methods. While other, non-async methods guarantee the execution order of scheduled tasks and always execute scheduled tasks on the same thread, this method does not guarantee this.

Specified by:

runDelayedAsync in interface ProcessingScheduleService

Parameters:

delay - The delay to wait before executing the task

task - The task to execute after the delay

runAtAsync

public SimpleProcessingScheduleService.ScheduledTask runAtAsync(long timestamp,
 Task task)

Description copied from interface: ProcessingScheduleService

Schedule a task to execute at or after a specific timestamp. The task is executed after the timestamp is passed. No guarantee is provided that the task is run exactly at the timestamp, but we guarantee that it is not executed before.

The execution of the scheduled task is running asynchronously/concurrently to task scheduled through non-async methods. While other, non-async methods guarantee the execution order of scheduled tasks and always execute scheduled tasks on the same thread, this method does not guarantee this.

Specified by:

runAtAsync in interface ProcessingScheduleService

Parameters:

timestamp - Unix epoch timestamp in milliseconds

task - The task to execute at or after the timestamp

runDelayed

public SimpleProcessingScheduleService.ScheduledTask runDelayed(Duration delay,
 Runnable task)

Description copied from interface: SimpleProcessingScheduleService

Schedules the task to run after the given delay.

Specified by:

runDelayed in interface SimpleProcessingScheduleService

Returns:

A representation of the scheduled task.

runDelayed

public SimpleProcessingScheduleService.ScheduledTask runDelayed(Duration delay,
 Task task)

Description copied from interface: SimpleProcessingScheduleService

Schedules the task to run after the given delay.

Specified by:

runDelayed in interface SimpleProcessingScheduleService

Returns:

A representation of the scheduled task.

runAt

public SimpleProcessingScheduleService.ScheduledTask runAt(long timestamp,
 Task task)

Description copied from interface: SimpleProcessingScheduleService

Schedules the task to run at or after the given timestamp.

Specified by:

runAt in interface SimpleProcessingScheduleService

Returns:

A representation of the scheduled task.

runAt

public SimpleProcessingScheduleService.ScheduledTask runAt(long timestamp,
 Runnable task)

Description copied from interface: SimpleProcessingScheduleService

Schedules the task to run at or after the given timestamp.

Specified by:

runAt in interface SimpleProcessingScheduleService

Returns:

A representation of the scheduled task.

runAtFixedRate

public void runAtFixedRate(Duration delay,
 Task task)

Specified by:

runAtFixedRate in interface SimpleProcessingScheduleService
