# ExplicitOuterTransformer

#### class ExplicitOuterTransformer extends OuterPathTransformer

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.
