Summary: Clean up RexWindowBound
Key: OPTIQ-315
URL: https://issues.apache.org/jira/browse/OPTIQ-315
Project: optiq
Issue Type: Bug
Reporter: Julian Hyde
Assignee: Julian Hyde
Clean up RexWindowBound. It contains both SqlNode and RexNode instances, so
lies uneasily across the SqlNode "parse tree" and RexNode "relational algebra"
layers. Creating a RexWindowBound requires both a SqlNode and a RexNode,
containing similar information.
Please revisit the class and make it depend upon just RexNode, and simplify the
factory routines.
