override def transformDefDef(tree: DefDef)(using Context): DefDef

If this is a constructor of a enum class that extends, add $name and $ordinal parameters to it.

def transformInfo(tp: Type, sym: Symbol)(using Context): Type
override def transformTemplate(templ: Template)(using Context): Tree
  1. If this is an enum class, add $name and $ordinal parameters to its parameter accessors and pass them on to the java.lang.Enum constructor.

  2. If this is an anonymous class that implement a singleton enum case, pass $name and $ordinal parameters to the enum superclass. The class looks like this:

    class $anon extends E(...) { ... }

    After the transform it is expanded to

    class $anon extends E(..., $name, _$ordinal) { // if class implements a simple enum case "same as before" }

    class $anon extends E(..., "A", 0) { // if class implements a value enum case A with ordinal 0 "same as before" }

protected def infoMayChange(sym: Symbol)(using Context): Boolean

Denotations with a symbol where infoMayChange is false are guaranteed to be unaffected by this transform, so transformInfo need not be run. This can save time, and more importantly, can help avoid forcing symbol completers.

Is this phase the standard typerphase? True for TyperPhase, but not for other first phases (such as FromTasty or Parser). The predicate is tested in some places that perform checks and corrections. It's different from ctx.isAfterTyper (and cheaper to test).
