initializeOutputOI

public void initializeOutputOI()
                        throws HiveException

Description copied from class: TableFunctionResolver

This method is invoked during runtime(during deserialization of theQueryDef). At this point the TableFunction can assume that the Expression Nodes exist for all the Def (ArgDef, ColumnDef, WindowDef..). It is the responsibility of the TableFunction to construct the evaluators and setup the OI.

Specified by:

initializeOutputOI in class TableFunctionResolver

Throws:

HiveException
