    • withHints

      public RelNode withHints(List<RelHint> hintList)
      Description copied from interface: Hintable
      Returns a new relational expression with the specified hints hintList.

      This method should be overridden by every logical node that supports hint. It is only for internal use during decorrelation.

      Sub-class should return a new copy of the relational expression.

      The default implementation returns the relational expression directly only because not every kind of relational expression supports hints.
