  5. def buildMultiColumnNone(tpe: Type): Node

    Create a Node representing a structure of null values of the given Type

  6. def collectDiscriminatorCandidates(n: Node): Set[(TypeSymbol, List[TermSymbol])]

    Collect discriminator candidate fields in a predicate.

    Collect discriminator candidate fields in a predicate. These are all paths below an OptionApply, which indicates their future use under a discriminator guard.

  8. def expandConditionals(n: Node): Node

    Expand multi-column conditional expressions and SilentCasts.

    Expand multi-column conditional expressions and SilentCasts. Single-column conditionals involving NULL values are optimized away where possible.

  9. def expandSums(n: Node): Node
  10. def fuse(n: Node): Node

    Fuse unnecessary Option operations

  12. def silentCast(tpe: Type, n: Node): Node

    Create a SilentCast call unless the type already matches

  13. def toOptionColumns(tpe: Type): Type

    Strip nominal types and convert all atomic types to OptionTypes

  14. def toString(): String

  15. def trType(tpe: Type): Type

    Perform the sum expansion on a Type

  16. def translateJoin(bind: Bind, discCandidates: Set[(TypeSymbol, List[TermSymbol])]): Bind

    Translate an Option-extended left outer, right outer or full outer join
