SimpleTimerService

public SimpleTimerService(InternalTimerService<org.apache.flink.runtime.state.VoidNamespace> internalTimerService)

方法详细资料

currentProcessingTime

public long currentProcessingTime()

从接口复制的说明: TimerService

Returns the current processing time.

指定者:

currentProcessingTime 在接口中 TimerService

currentWatermark

public long currentWatermark()

从接口复制的说明: TimerService

Returns the current event-time watermark.

指定者:

currentWatermark 在接口中 TimerService

registerProcessingTimeTimer

public void registerProcessingTimeTimer(long time)

从接口复制的说明: TimerService

Registers a timer to be fired when processing time passes the given time.

Timers can internally be scoped to keys and/or windows. When you set a timer in a keyed context, such as in an operation on KeyedStream then that context will also be active when you receive the timer notification.

指定者:

registerProcessingTimeTimer 在接口中 TimerService

registerEventTimeTimer

public void registerEventTimeTimer(long time)

从接口复制的说明: TimerService

Registers a timer to be fired when the event time watermark passes the given time.

Timers can internally be scoped to keys and/or windows. When you set a timer in a keyed context, such as in an operation on KeyedStream then that context will also be active when you receive the timer notification.

指定者:

registerEventTimeTimer 在接口中 TimerService

deleteProcessingTimeTimer

public void deleteProcessingTimeTimer(long time)

从接口复制的说明: TimerService

Deletes the processing-time timer with the given trigger time. This method has only an effect if such a timer was previously registered and did not already expire.

Timers can internally be scoped to keys and/or windows. When you delete a timer, it is removed from the current keyed context.

指定者:

deleteProcessingTimeTimer 在接口中 TimerService

deleteEventTimeTimer

public void deleteEventTimeTimer(long time)

从接口复制的说明: TimerService

Deletes the event-time timer with the given trigger time. This method has only an effect if such a timer was previously registered and did not already expire.

Timers can internally be scoped to keys and/or windows. When you delete a timer, it is removed from the current keyed context.

指定者:
