| /** |
| * TypeVariable is the common superinterface for type variables of kinds. |
| * A type variable is created the first time it is needed by a reflective |
| * method, as specified in this package. If a type variable t is referenced |
| * by a type (i.e, class, interface or annotation type) T, and T is declared |
| * by the nth enclosing class of T (see JLS 8.1.2), then the creation of t |
| * requires the resolution (see JVMS 5) of the ith enclosing class of T, |
| * for i = 0 to n, inclusive. Creating a type variable must not cause the |
| * creation of its bounds. Repeated creation of a type variable has no effect. |
| * |
| * <p>Multiple objects may be instantiated at run-time to |
| * represent a given type variable. Even though a type variable is |
| * created only once, this does not imply any requirement to cache |
| * instances representing the type variable. However, all instances |
| * representing a type variable must be equal() to each other. |
| * As a consequence, users of type variables must not rely on the identity |
| * of instances of classes implementing this interface. |
| * |
| * @param <D> the type of generic declaration that declared the |
| * underlying type variable. |
