- 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.
