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<RowData>

Overrides:

open in class AbstractStreamArrowPythonOverWindowAggregateFunctionOperator<K>

Throws:

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

onEventTime

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

Description copied from interface: Triggerable

Invoked when an event-time timer fires.

Throws:

Exception

onProcessingTime

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

Description copied from interface: Triggerable

Invoked when a processing-time timer fires.

Throws:

Exception

emitResult

public void emitResult(Tuple3<String,byte[],Integer> resultTuple)
                throws Exception

Description copied from class: AbstractExternalPythonFunctionOperator

Sends the execution result to the downstream operator.

Specified by:

emitResult in class AbstractExternalPythonFunctionOperator<RowData>

Throws:

Exception
