aoqi@0 34 * A skeletal visitor of program elements with default behavior
aoqi@0 35 * appropriate for the {@link SourceVersion#RELEASE_7 RELEASE_7}
aoqi@0 36 * source version.
aoqi@0 37 *
aoqi@0 38 * <p> <b>WARNING:</b> The {@code ElementVisitor} interface
aoqi@0 39 * implemented by this class may have methods added to it in the
aoqi@0 40 * future to accommodate new, currently unknown, language structures
aoqi@0 41 * added to future versions of the Java&trade; programming language.
aoqi@0 42 * Therefore, methods whose names begin with {@code "visit"} may be
aoqi@0 43 * added to this class in the future; to avoid incompatibilities,
aoqi@0 44 * classes which extend this class should not declare any instance
aoqi@0 45 * methods with names beginning with {@code "visit"}.
aoqi@0 46 *
aoqi@0 47 * <p>When such a new visit method is added, the default
aoqi@0 48 * implementation in this class will be to call the {@link
aoqi@0 49 * #visitUnknown visitUnknown} method. A new abstract element visitor
aoqi@0 50 * class will also be introduced to correspond to the new language
aoqi@0 51 * level; this visitor will have different default behavior for the
aoqi@0 52 * visit method in question. When the new visitor is introduced, all
aoqi@0 53 * or portions of this visitor may be deprecated.
aoqi@0 54 *
aoqi@0 55 * <p>Note that adding a default implementation of a new visit method
aoqi@0 56 * in a visitor class will occur instead of adding a <em>default
aoqi@0 57 * method</em> directly in the visitor interface since a Java SE 8
aoqi@0 58 * language feature cannot be used to this version of the API since
aoqi@0 59 * this version is required to be runnable on Java SE 7
aoqi@0 60 * implementations. Future versions of the API that are only required
aoqi@0 61 * to run on Java SE 8 and later may take advantage of default methods
aoqi@0 62 * in this situation.
aoqi@0 63 *
aoqi@0 64 * @param <R> the return type of this visitor's methods. Use {@link
aoqi@0 65 * Void} for visitors that do not need to return results.
aoqi@0 66 * @param <P> the type of the additional parameter to this visitor's
aoqi@0 67 * methods. Use {@code Void} for visitors that do not need an
aoqi@0 68 * additional parameter.
aoqi@0 69 *
aoqi@0 70 * @see AbstractElementVisitor6
aoqi@0 71 * @see AbstractElementVisitor8
