/** |
|
31 |
* A TreeVisitor that visits all the child tree nodes. |
|
32 |
* To visit nodes of a particular type, just override the |
|
33 |
* corresponding visitXYZ method. |
|
34 |
* Inside your method, call super.visitXYZ to visit descendant |
|
35 |
* nodes. |
|
36 |
* |
|
37 |
* <p>The default implementation of the visitXYZ methods will determine |
|
38 |
* a result as follows: |
|
39 |
* <ul> |
|
25287 | 40 |
* <li>If the node being visited has no children, the result will be {@code null}. |
10 | 41 |
* <li>If the node being visited has one child, the result will be the |
42 |
* result of calling {@code scan} on that child. The child may be a simple node |
|
43 |
* or itself a list of nodes. |
|
44 |
* <li> If the node being visited has more than one child, the result will |
|
45 |
* be determined by calling {@code scan} each child in turn, and then combining the |
|
46 |
* result of each scan after the first with the cumulative result |
|
47 |
* so far, as determined by the {@link #reduce} method. Each child may be either |
|
48 |
* a simple node of a list of nodes. The default behavior of the {@code reduce} |
|
49 |
* method is such that the result of the visitXYZ method will be the result of |
|
50 |
* the last child scanned. |
|
51 |
* </ul> |
|
52 |
* |
|
53 |
* <p>Here is an example to count the number of identifier nodes in a tree: |
|
54 |
* <pre> |
|
13844 | 55 |
* class CountIdentifiers extends TreeScanner<Integer,Void> { |
10 | 56 |
* {@literal @}Override |
57 |
* public Integer visitIdentifier(IdentifierTree node, Void p) { |
|
58 |
* return 1; |
|
59 |
* } |
|
60 |
* {@literal @}Override |
|
61 |
* public Integer reduce(Integer r1, Integer r2) { |
|
62 |
* return (r1 == null ? 0 : r1) + (r2 == null ? 0 : r2); |
|
63 |
* } |
|
64 |
* } |
|
65 |
* </pre> |
|
66 |
* |
|
25287 | 67 |
* @param <R> the return type of this visitor's methods. Use {@link |
68 |
* Void} for visitors that do not need to return results. |
|
69 |
* @param <P> the type of the additional parameter to this visitor's |
|
70 |
* methods. Use {@code Void} for visitors that do not need an |
|
71 |
* additional parameter. |
