/**
* 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.
