def accessorNamed(name: TermName)(using Context): Symbol

The declared self type of this class, as seen from site, stripping all refinements for opaque types.

Attributes

def deriveTargetNameAnnotation(original: Symbol, nameFn: Name => Name)(using Context): Unit

If original has a target name annotation, add one to this symbol as well such that the new target name is original's target name transformed by nameFn.

Attributes

All traits implemented by a class or trait except for those inherited through the superclass. Traits are given in the order they appear in the parents clause (which is the reverse of their order in baseClasses)
