| darcy@575 | 35 | * A simple visitor of program elements with default behavior |
| darcy@575 | 36 | * appropriate for the {@link SourceVersion#RELEASE_7 RELEASE_7} |
| darcy@575 | 37 | * source version. |
| darcy@575 | 38 | * |
| darcy@575 | 39 | * Visit methods corresponding to {@code RELEASE_7} language |
| darcy@575 | 40 | * constructs call {@link #defaultAction}, passing their arguments to |
| darcy@575 | 41 | * {@code defaultAction}'s corresponding parameters. |
| darcy@575 | 42 | * |
| darcy@575 | 43 | * <p> Methods in this class may be overridden subject to their |
| darcy@575 | 44 | * general contract. Note that annotating methods in concrete |
| darcy@575 | 45 | * subclasses with {@link java.lang.Override @Override} will help |
| darcy@575 | 46 | * ensure that methods are overridden as intended. |
| darcy@575 | 47 | * |
| darcy@575 | 48 | * <p> <b>WARNING:</b> The {@code ElementVisitor} interface |
| darcy@575 | 49 | * implemented by this class may have methods added to it in the |
| darcy@575 | 50 | * future to accommodate new, currently unknown, language structures |
| darcy@575 | 51 | * added to future versions of the Java™ programming language. |
| darcy@575 | 52 | * Therefore, methods whose names begin with {@code "visit"} may be |
| darcy@575 | 53 | * added to this class in the future; to avoid incompatibilities, |
| darcy@575 | 54 | * classes which extend this class should not declare any instance |
| darcy@575 | 55 | * methods with names beginning with {@code "visit"}. |
| darcy@575 | 56 | * |
| darcy@575 | 57 | * <p>When such a new visit method is added, the default |
| darcy@575 | 58 | * implementation in this class will be to call the {@link |
| darcy@575 | 59 | * #visitUnknown visitUnknown} method. A new simple element visitor |
| darcy@575 | 60 | * class will also be introduced to correspond to the new language |
| darcy@575 | 61 | * level; this visitor will have different default behavior for the |
| darcy@575 | 62 | * visit method in question. When the new visitor is introduced, all |
| darcy@575 | 63 | * or portions of this visitor may be deprecated. |
| darcy@575 | 64 | * |
| darcy@575 | 65 | * @param <R> the return type of this visitor's methods. Use {@code Void} |
| darcy@575 | 66 | * for visitors that do not need to return results. |
| darcy@575 | 67 | * @param <P> the type of the additional parameter to this visitor's methods. Use {@code Void} |
| darcy@575 | 68 | * for visitors that do not need an additional parameter. |
| darcy@575 | 69 | * |
