方法概要

限定符和类型	方法和说明
void	onProcessingTime(long timestamp) 已过时。 This method is invoked with the timestamp for which the trigger was scheduled.
void	open() 已过时。 This method is called immediately before any elements are processed, it should contain the operator's initialization logic, e.g. state initialization.
void	processElement(StreamRecord<T> element) 已过时。 Processes one element that arrived at this operator.
void	processWatermark(Watermark mark) 已过时。 Processes a Watermark.

方法详细资料

open

public void open()
          throws Exception

已过时。

从类复制的说明: AbstractStreamOperator

This method is called immediately before any elements are processed, it should contain the operator's initialization logic, e.g. state initialization.

The default implementation does nothing.

指定者:

open 在接口中 StreamOperator<T>

覆盖:

open 在类中 AbstractUdfStreamOperator<T,TimestampExtractor<T>>

抛出:

Exception - An exception in this method causes the operator to fail.

processElement

public void processElement(StreamRecord<T> element)
                    throws Exception

已过时。

从接口复制的说明: OneInputStreamOperator

Processes one element that arrived at this operator. This method is guaranteed to not be called concurrently with other methods of the operator.

指定者:

processElement 在接口中 OneInputStreamOperator<T,T>

抛出:

Exception

onProcessingTime

public void onProcessingTime(long timestamp)
                      throws Exception

已过时。

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

processWatermark

public void processWatermark(Watermark mark)
                      throws Exception

已过时。

从接口复制的说明: OneInputStreamOperator

Processes a Watermark. This method is guaranteed to not be called concurrently with other methods of the operator.

指定者:

processWatermark 在接口中 OneInputStreamOperator<T,T>

覆盖:

processWatermark 在类中 AbstractStreamOperator<T>

抛出:

Exception
