[jtkiesel]

What changed with this PR:

Fixes some issues with constructor receiver parameters, and added support for method receiver parameters.

Example

Input

class Currency {
  Currency(Currency this) {}

  Currency(Currency this, Currency other) {}

  Currency(@AnnotatedUsage Currency this, Currency other) {}

  Currency(@AnnotatedUsage Currency this, String aaaaaaaaaa, String bbbbbbbbbb) {}

  String getCode(Currency this) {}

  int compareTo(Currency this, Currency other) {}

  int compareTo(@AnnotatedUsage Currency this, Currency other) {}

  int compareTo(@AnnotatedUsage Currency this, String aaaaaaaaaa, String bbbbbbbbbb) {}

  class Inner {
    Inner(Currency Currency.this) {}

    String getCode(Currency Currency.this) {}
  }
}

Output

class Currency {

  Currency(Currency this) {}

  Currency(Currency this, Currency other) {}

  Currency(@AnnotatedUsage Currency this, Currency other) {}

  Currency(
    @AnnotatedUsage Currency this,
    String aaaaaaaaaa,
    String bbbbbbbbbb
  ) {}

  String getCode(Currency this) {}

  int compareTo(Currency this, Currency other) {}

  int compareTo(@AnnotatedUsage Currency this, Currency other) {}

  int compareTo(
    @AnnotatedUsage Currency this,
    String aaaaaaaaaa,
    String bbbbbbbbbb
  ) {}

  class Inner {

    Inner(Currency Currency.this) {}

    String getCode(Currency Currency.this) {}
  }
}
