RelFieldTrimmer.TrimResult Result of an attempt to trim columns from a relational expression.
RelStructuredTypeFlattener RelStructuredTypeFlattener removes all structured types from a tree of relational expressions.
RelStructuredTypeFlattener.SelfFlatteningRel Mix-in interface for relational expressions that know how to flatten themselves.
SqlNodeToRexConverter Converts expressions from SqlNode to RexNode.
SqlRexContext Contains the context necessary for a SqlRexConvertlet to convert a SqlNode expression into a RexNode.
