| 34 * A simple visitor of types with default behavior appropriate for the | |
| 35 * {@link SourceVersion#RELEASE_7 RELEASE_7} source version. | |
| 36 * | |
| 37 * Visit methods corresponding to {@code RELEASE_7} language | |
| 38 * constructs call {@link #defaultAction}, passing their arguments to | |
| 39 * {@code defaultAction}'s corresponding parameters. | |
| 40 * | |
| 41 * <p> Methods in this class may be overridden subject to their | |
| 42 * general contract. Note that annotating methods in concrete | |
| 43 * subclasses with {@link java.lang.Override @Override} will help | |
| 44 * ensure that methods are overridden as intended. | |
| 45 * | |
| 46 * <p> <b>WARNING:</b> The {@code TypeVisitor} interface implemented | |
| 47 * by this class may have methods added to it in the future to | |
| 48 * accommodate new, currently unknown, language structures added to | |
| 49 * future versions of the Java™ programming language. | |
| 50 * Therefore, methods whose names begin with {@code "visit"} may be | |
| 51 * added to this class in the future; to avoid incompatibilities, | |
| 52 * classes which extend this class should not declare any instance | |
| 53 * methods with names beginning with {@code "visit"}. | |
| 54 * | |
| 55 * <p>When such a new visit method is added, the default | |
| 56 * implementation in this class will be to call the {@link | |
| 57 * #visitUnknown visitUnknown} method. A new simple type visitor | |
| 58 * class will also be introduced to correspond to the new language | |
| 59 * level; this visitor will have different default behavior for the | |
| 60 * visit method in question. When the new visitor is introduced, all | |
| 61 * or portions of this visitor may be deprecated. | |
| 62 * | |
| 63 * @param <R> the return type of this visitor's methods. Use {@link | |
| 64 * Void} for visitors that do not need to return results. | |
| 65 * @param <P> the type of the additional parameter to this visitor's | |
| 66 * methods. Use {@code Void} for visitors that do not need an | |
| 67 * additional parameter. | |
| 68 * | |
| 69 * @see SimpleTypeVisitor6 | |
| 70 * @since 1.7 | |
