/**

 * <p>

 * Compile-time representation of Java type system.

 *

 * <p>

 * These classes are used as TypeT and ClassDeclT of the model parameterization. This implementaion is designed to be

 * capable of representing pre-existing classes (such as java.lang.String) as well as the generated classes (represented

 * as JDefinedClass.)

 *

 * <h2>Handling of Primitive Types</h2>

 * <p>

 * Primitive types have two forms (int and Integer), and this complicates the binding process. For this reason, inside

 * the front end, we always use the boxed types. We'll use the unboxed form only in the back end when we know the field

 * doesn't need to represent the null value.
