duke@1 33 * Represents a class or interface program element. Provides access
duke@1 34 * to information about the type and its members. Note that an enum
duke@1 35 * type is a kind of class and an annotation type is a kind of
duke@1 36 * interface.
duke@1 37 *
duke@1 38 * <p> <a name="ELEM_VS_TYPE"></a>
duke@1 39 * While a {@code TypeElement} represents a class or interface
duke@1 40 * <i>element</i>, a {@link DeclaredType} represents a class
duke@1 41 * or interface <i>type</i>, the latter being a use
duke@1 42 * (or <i>invocation</i>) of the former.
duke@1 43 * The distinction is most apparent with generic types,
duke@1 44 * for which a single element can define a whole
duke@1 45 * family of types. For example, the element
duke@1 46 * {@code java.util.Set} corresponds to the parameterized types
duke@1 47 * {@code java.util.Set<String>} and {@code java.util.Set<Number>}
duke@1 48 * (and many others), and to the raw type {@code java.util.Set}.
duke@1 49 *
duke@1 50 * <p> Each method of this interface that returns a list of elements
duke@1 51 * will return them in the order that is natural for the underlying
duke@1 52 * source of program information. For example, if the underlying
duke@1 53 * source of information is Java source code, then the elements will be
duke@1 54 * returned in source code order.
