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<Object>

Overrides:

open in class TableStreamOperator<Object>

Throws:

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

processElement

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

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<RowData>

Throws:

Exception
