  /**
   * Types and hierarchies of packages comprising a {@index "Java language
   * model"}, a model of the declarations and types of the Java
   * programming language.
   *
   * The members of this package and its subpackages are for use in
   * language modeling and language processing tasks and APIs including,
   * but not limited to, the {@linkplain jdkx.annotation.processing
   * annotation processing} framework.
   *
   * <p> This language model follows a <i>mirror</i>-based design; see
   *
   * <blockquote>
   * Gilad Bracha and David Ungar. <i>Mirrors: Design Principles for
   * Meta-level Facilities of Object-Oriented Programming Languages</i>.
   * In Proc. of the ACM Conf. on Object-Oriented Programming, Systems,
   * Languages and Applications, October 2004.
   * </blockquote>
   *
   * In particular, the model makes a distinction between declared
   * language constructs, like the {@linkplain jdkx.lang.model.element
   * element} representing {@code java.util.Set}, and the family of
   * {@linkplain jdkx.lang.model.type types} that may be associated
   * with an element, like the raw type {@code java.util.Set}, {@code
   * java.util.Set<String>}, and {@code java.util.Set<T>}.
   *
   * <p>Unless otherwise specified, methods in this package will throw
   * a {@code NullPointerException} if given a {@code null} argument.
