| aoqi@0 | 29 | * A visitor of trees, in the style of the visitor design pattern. |
| aoqi@0 | 30 | * Classes implementing this interface are used to operate |
| aoqi@0 | 31 | * on a tree when the kind of tree is unknown at compile time. |
| aoqi@0 | 32 | * When a visitor is passed to an tree's {@link Tree#accept |
| aoqi@0 | 33 | * accept} method, the <tt>visit<i>XYZ</i></tt> method most applicable |
| aoqi@0 | 34 | * to that tree is invoked. |
| aoqi@0 | 35 | * |
| aoqi@0 | 36 | * <p> Classes implementing this interface may or may not throw a |
| aoqi@0 | 37 | * {@code NullPointerException} if the additional parameter {@code p} |
| aoqi@0 | 38 | * is {@code null}; see documentation of the implementing class for |
| aoqi@0 | 39 | * details. |
| aoqi@0 | 40 | * |
| aoqi@0 | 41 | * <p> <b>WARNING:</b> It is possible that methods will be added to |
| aoqi@0 | 42 | * this interface to accommodate new, currently unknown, language |
| aoqi@0 | 43 | * structures added to future versions of the Java™ programming |
| aoqi@0 | 44 | * language. Therefore, visitor classes directly implementing this |
| aoqi@0 | 45 | * interface may be source incompatible with future versions of the |
| aoqi@0 | 46 | * platform. |
| aoqi@0 | 47 | * |
| aoqi@0 | 48 | * @param <R> the return type of this visitor's methods. Use {@link |
| aoqi@0 | 49 | * Void} for visitors that do not need to return results. |
| aoqi@0 | 50 | * @param <P> the type of the additional parameter to this visitor's |
| aoqi@0 | 51 | * methods. Use {@code Void} for visitors that do not need an |
| aoqi@0 | 52 | * additional parameter. |
