方法概要

限定符和类型	方法和说明
void	onEventTime(InternalTimer<K,org.apache.flink.runtime.state.VoidNamespace> timer) 已过时。 Invoked when an event-time timer fires.
void	onProcessingTime(InternalTimer<K,org.apache.flink.runtime.state.VoidNamespace> timer) 已过时。 Invoked when a processing-time timer fires.
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<IN> element) 已过时。 Processes one element that arrived at this operator.

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<OUT>

覆盖:

open 在类中 AbstractUdfStreamOperator<OUT,ProcessFunction<IN,OUT>>

抛出:

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

onEventTime

public void onEventTime(InternalTimer<K,org.apache.flink.runtime.state.VoidNamespace> timer)
                 throws Exception

已过时。

从接口复制的说明: Triggerable

Invoked when an event-time timer fires.

指定者:

onEventTime 在接口中 Triggerable<K,org.apache.flink.runtime.state.VoidNamespace>

抛出:

Exception

onProcessingTime

public void onProcessingTime(InternalTimer<K,org.apache.flink.runtime.state.VoidNamespace> timer)
                      throws Exception

已过时。

从接口复制的说明: Triggerable

Invoked when a processing-time timer fires.

指定者:

onProcessingTime 在接口中 Triggerable<K,org.apache.flink.runtime.state.VoidNamespace>

抛出:

Exception

processElement

public void processElement(StreamRecord<IN> 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<IN,OUT>

抛出:

Exception
