Method Summary

Modifier and Type	Method and Description
void	onEventTime(InternalTimer<K,org.apache.flink.runtime.state.VoidNamespace> timer) Deprecated. Invoked when an event-time timer fires.
void	onProcessingTime(InternalTimer<K,org.apache.flink.runtime.state.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.
void	processElement(StreamRecord<IN> element) Deprecated. Processes one element that arrived on this input of the MultipleInputStreamOperator.

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<OUT>

Overrides:

open in class AbstractUdfStreamOperator<OUT,ProcessFunction<IN,OUT>>

Throws:

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

Deprecated.

Description copied from interface: Triggerable

Invoked when an event-time timer fires.

Specified by:

onEventTime in interface Triggerable<K,org.apache.flink.runtime.state.VoidNamespace>

Throws:

Exception

onProcessingTime

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

Deprecated.

Description copied from interface: Triggerable

Invoked when a processing-time timer fires.

Specified by:

onProcessingTime in interface Triggerable<K,org.apache.flink.runtime.state.VoidNamespace>

Throws:

Exception

processElement

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

Deprecated.

Description copied from interface: Input

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

Specified by:

processElement in interface Input<IN>

Throws:

Exception
