Method Detail

open

public void open()
          throws Exception

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<KEY>

Overrides:

open in class TwoInputBroadcastProcessOperator<IN1,IN2,OUT>

Throws:

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

getOutputCollector

protected TimestampCollector<OUT> getOutputCollector()

Overrides:

getOutputCollector in class TwoInputBroadcastProcessOperator<IN1,IN2,OUT>

currentKey

protected Object currentKey()

Overrides:

currentKey in class TwoInputBroadcastProcessOperator<IN1,IN2,OUT>

getProcessingTimeManager

protected ProcessingTimeManager getProcessingTimeManager()

Overrides:

Specified by:

onEventTime in interface Triggerable<KEY,IN1>

Throws:

Exception

onProcessingTime

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