    27  * Classes and hierarchies of packages used to model the Java

    28  * programming language.

    29  *

    30  * The members of this package and its subpackages are for use in

    31  * language modeling and language processing tasks and APIs including,

    32  * but not limited to, the {@linkplain javax.annotation.processing

    33  * annotation processing} framework.

    34  *

    35  * <p> This language model follows a <i>mirror</i>-based design; see

    36  *

    37  * <blockquote>

    38  * Gilad Bracha and David Ungar. <i>Mirrors: Design Principles for

    39  * Meta-level Facilities of Object-Oriented Programming Languages</i>.

    40  * In Proc. of the ACM Conf. on Object-Oriented Programming, Systems,

    41  * Languages and Applications, October 2004.

    42  * </blockquote>

    43  *

    44  * In particular, the model makes a distinction between static

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

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

    47  * {@linkplain javax.lang.model.type types} that may be associated

    48  * with an element, like the raw type {@code java.util.Set}, {@code

    49  * java.util.Set<String>}, and {@code java.util.Set<T>}.

    50  *

    51  * <p> Unless otherwise specified, methods in this package will throw

    52  * a {@code NullPointerException} if given a {@code null} argument.
