Type Members

  1. final case class Aligned(patterns: Patterns, extractor: Extractor) extends Product with Serializable

    If elementArity is.

  2. final case class Extractor(whole: Type, fixed: List[Type], repeated: Repeated) extends Product with Serializable

    An 'extractor' can be a case class or an unapply or unapplySeq method.

  3. final case class Patterns(fixed: List[Pattern], star: Pattern) extends Product with Serializable

    Definition Classes
    PatternExpander

  4. sealed case class Repeated(sequenceType: Type, elementType: Type, repeatedType: Type) extends Product with Serializable

    It's not optimal that we're carrying both sequence and repeated type here, but the implementation requires more unraveling before it can be avoided.

  5. final case class TypedPat(pat: Pattern, tpe: Type) extends Product with Serializable

    Definition Classes
    PatternExpander

    You'll note we're not inside the cake. "Pattern" and "Type" are arbitrary types here, and NoPattern and NoType arbitrary values.

  9. def applyMethodTypes(method: Global.Type): Extractor

    In this case we are basing the pattern expansion on a case class constructor.

    In this case, expansion is based on an unapply or unapplySeq method. Unfortunately the MethodType does not carry the information of whether it was unapplySeq, so we have to funnel that information in separately.
