Undefined (Groovy 3.0.7)

Package groovy.transform

## Class Undefined

- java.lang.Object
- - groovy.transform.Undefined

-     public final class Undefined
      extends Object

  Java doesn't allow you to have null as an attribute value. It wants you to indicate what you really mean by null, so that is what we do here - as ugly as it is.
