Method Detail

open

public void open()
          throws Exception

Description copied from class: AbstractStreamOperator

The default implementation does nothing.

Specified by:

open in interface StreamOperator<KEY>

Overrides:

open in class TwoInputNonBroadcastProcessOperator<IN1,IN2,OUT>

Throws:

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

getOutputCollector

protected TimestampCollector<OUT> getOutputCollector()

Overrides:

getOutputCollector in class TwoInputNonBroadcastProcessOperator<IN1,IN2,OUT>

currentKey

protected Object currentKey()

Overrides:

currentKey in class TwoInputNonBroadcastProcessOperator<IN1,IN2,OUT>

getProcessingTimeManager

protected ProcessingTimeManager getProcessingTimeManager()

Overrides:

getProcessingTimeManager in class TwoInputNonBroadcastProcessOperator<IN1,IN2,OUT>

onEventTime

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

Description copied from interface: Triggerable

Invoked when an event-time timer fires.

Specified by:

onEventTime in interface Triggerable<KEY,IN1>

Throws:

Exception

onProcessingTime

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