| /** |
| * A visitor of trees, in the style of the visitor design pattern. |
| * Classes implementing this interface are used to operate |
| * on a tree when the kind of tree is unknown at compile time. |
| * When a visitor is passed to an tree's {@link Tree#accept |
| * accept} method, the <tt>visit<i>XYZ</i></tt> method most applicable |
| * to that tree is invoked. |
| * |
| * <p> Classes implementing this interface may or may not throw a |
| * {@code NullPointerException} if the additional parameter {@code p} |
| * is {@code null}; see documentation of the implementing class for |
| * details. |
| * |
| * <p> <b>WARNING:</b> It is possible that methods will be added to |
| * this interface to accommodate new, currently unknown, language |
| * structures added to future versions of the Java™ programming |
| * language. Therefore, visitor classes directly implementing this |
| * interface may be source incompatible with future versions of the |
| * platform. |
| * |
| * @param <R> the return type of this visitor's methods. Use {@link |
| * Void} for visitors that do not need to return results. |
| * @param <P> the type of the additional parameter to this visitor's |
| * methods. Use {@code Void} for visitors that do not need an |
| * additional parameter. |
