The following properties are reported:

Top-level properties

Example:

  // top-level property
  val USER_NAME_FIELD = "UserName"
  // top-level property holding reference to singleton object
  val PersonComparator: Comparator<Person> = /*...*/

  class Person {
    companion object {
      // property in companion object
      val NO_NAME = Person()
    }
  }
