The phase performs the following transformations on terms:
-
An class which is not an interface and is not static gets an outer accessor (@see outerDefs).
1a. A class which is not a trait gets an outer field.
- A constructor of a non-trait inner class gets an outer parameter.
- A reference C.this where C refers to an outer class is replaced by a selection this.$outer$$C1 ... .$outer$$Cn (@see outerPath)
-
- A call to a constructor Q.<init>(args) or Q.$init$(args) where Q != this and the constructor belongs to a non-static class is augmented by an outer argument. E.g. Q.<init>(OUTER, args) where OUTER is the qualifier corresponding to the singleton type Q.
- A call to a constructor this.<init>(args) in a secondary constructor is augmented to this.<init>(OUTER, args) where OUTER is the last parameter of the secondary constructor.
- Remove private modifier from class members M that are accessed from an inner class.
- Remove protected modifier from class members M that are accessed without a super qualifier accessed from an inner class or trait.
- Remove private and protected modifiers from type symbols
- Remove private modifiers from members of traits
Note: The whole transform is run in phase explicitOuter.next.
