-/**
- * Type node for a qualified type (added in JLS3 API).
- * <pre>
- * QualifiedType:
- * Type <b>.</b> SimpleName
- * </pre>
- * <p>
- * Not all node arragements will represent legal Java constructs. In particular,
- * it is nonsense if the type is an array type or primitive type. The normal use
- * is when the type is a simple or parameterized type.
- * </p>
- * <p>
- * A type like "A.B" can be represented either of two ways:
- * <ol>
- * <li>
- * <code>QualifiedType(SimpleType(SimpleName("A")),SimpleName("B"))</code>
- * </li>
- * <li>
- * <code>SimpleType(QualifiedName(SimpleName("A"),SimpleName("B")))</code>
- * </li>
- * </ol>
- * The first form is preferred when "A" is known to be a type. However, a
- * parser cannot always determine this. Clients should be prepared to handle
- * either rather than make assumptions. (Note also that the first form
- * became possible as of JLS3; only the second form existed in JLS2 API.)
- * </p>
- *
- * @since 3.1
- * @noinstantiate This class is not intended to be instantiated by clients.
