/**

 * Classes and hierarchies of packages used to model 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 javax.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 static

 * language constructs, like the {@linkplain javax.lang.model.element

 * element} representing {@code java.util.Set}, and the family of

 * {@linkplain javax.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.
