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 AbstractArrowPythonAggregateFunctionOperator

Throws:

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

processElementInternal

public void processElementInternal(RowData value)
                            throws Exception

Specified by:

processElementInternal in class AbstractStatelessFunctionOperator<RowData,RowData,RowData>

Throws:

Exception
