从接口复制的说明: ProcessingTimeCallback

This method is invoked with the timestamp for which the trigger was scheduled.

If the triggering is delayed for whatever reason (trigger timer was blocked, JVM stalled due to a garbage collection), the timestamp supplied to this function will still be the original timestamp for which the trigger was scheduled.

指定者:

onProcessingTime 在接口中 ProcessingTimeCallback

参数:

timestamp - The timestamp for which the trigger event was scheduled.

抛出:

Exception

onElement

public void onElement(IN value,
                      long currentProcessingTime,
                      @Nullable
                      Long elementTimestamp,
                      long currentWatermark)
               throws Exception

抛出:
