| 37 * A simple visitor for annotation values with default behavior | |
| 38 * appropriate for the {@link SourceVersion#RELEASE_8 RELEASE_8} | |
| 39 * source version. Visit methods call {@link #defaultAction | |
| 40 * defaultAction} passing their arguments to {@code defaultAction}'s | |
| 41 * corresponding parameters. | |
| 42 * | |
| 43 * <p> Methods in this class may be overridden subject to their | |
| 44 * general contract. Note that annotating methods in concrete | |
| 45 * subclasses with {@link java.lang.Override @Override} will help | |
| 46 * ensure that methods are overridden as intended. | |
| 47 * | |
| 48 * <p> <b>WARNING:</b> The {@code AnnotationValueVisitor} interface | |
| 49 * implemented by this class may have methods added to it in the | |
| 50 * future to accommodate new, currently unknown, language structures | |
| 51 * added to future versions of the Java™ programming language. | |
| 52 * Therefore, methods whose names begin with {@code "visit"} may be | |
| 53 * added to this class in the future; to avoid incompatibilities, | |
| 54 * classes which extend this class should not declare any instance | |
| 55 * methods with names beginning with {@code "visit"}. | |
| 56 * | |
| 57 * <p>When such a new visit method is added, the default | |
| 58 * implementation in this class will be to call the {@link | |
| 59 * #visitUnknown visitUnknown} method. A new simple annotation | |
| 60 * value visitor class will also be introduced to correspond to the | |
| 61 * new language level; this visitor will have different default | |
| 62 * behavior for the visit method in question. When the new visitor is | |
| 63 * introduced, all or portions of this visitor may be deprecated. | |
| 64 * | |
| 65 * @param <R> the return type of this visitor's methods | |
| 66 * @param <P> the type of the additional parameter to this visitor's methods. | |
