Method Summary

Modifier and Type	Method	Description
protected TimestampedCollector<OUT>	getCollector()	Deprecated.
void	onEventTime(InternalTimer<K,VoidNamespace> timer)	Deprecated. Invoked when an event-time timer fires.
void	onProcessingTime(InternalTimer<K,VoidNamespace> timer)	Deprecated. Invoked when a processing-time timer fires.
void	open()	Deprecated. This method is called immediately before any elements are processed, it should contain the operator's initialization logic, e.g. state initialization.

Method Detail

open

public void open()
          throws Exception

Deprecated.

Description copied from class: 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.

Specified by:

open in interface StreamOperator<K>

Overrides:

open in class AbstractUdfStreamOperator<OUT,CoProcessFunction<IN1,IN2,OUT>>

Throws:

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

processElement1

public void processElement1(StreamRecord<IN1> element)
                     throws Exception

Deprecated.

Description copied from interface: TwoInputStreamOperator

Processes one element that arrived on the first input of this two-input operator. This method is guaranteed to not be called concurrently with other methods of the operator.

Specified by:

processElement1 in interface TwoInputStreamOperator<K,IN1,IN2>

Throws:

Exception

processElement2

public void processElement2(StreamRecord<IN2> element)
                     throws Exception

Deprecated.

Description copied from interface: TwoInputStreamOperator

Processes one element that arrived on the second input of this two-input operator. This method is guaranteed to not be called concurrently with other methods of the operator.

Specified by:

processElement2 in interface TwoInputStreamOperator<K,IN1,IN2>

Throws:

Exception

onEventTime

public void onEventTime(InternalTimer<K,VoidNamespace> timer)
                 throws Exception

Deprecated.

Description copied from interface: Triggerable

Invoked when an event-time timer fires.

Specified by:

onEventTime in interface Triggerable<K,IN1>

Throws:

Exception

onProcessingTime

public void onProcessingTime(InternalTimer<K,VoidNamespace> timer)
                      throws Exception

Deprecated.

Description copied from interface: Triggerable

Invoked when a processing-time timer fires.

Specified by:

onProcessingTime in interface Triggerable<K,IN1>

Throws:

Exception

getCollector

protected TimestampedCollector<OUT> getCollector()

Deprecated.
