| 20 | /** |
| 21 | * Concrete superclass and default implementation of an AST subtree matcher. |
| 22 | * <p> |
| 23 | * For example, to compute whether two ASTs subtrees are structurally |
| 24 | * isomorphic, use <code>n1.subtreeMatch(new ASTMatcher(), n2)</code> where |
| 25 | * <code>n1</code> and <code>n2</code> are the AST root nodes of the subtrees. |
| 26 | * </p> |
| 27 | * <p> |
| 28 | * For each different concrete AST node type <i>T</i> there is a |
| 29 | * <code>public boolean match(<i>T</i> node, Object other)</code> method |
| 30 | * that matches the given node against another object (typically another |
| 31 | * AST node, although this is not essential). The default implementations |
| 32 | * provided by this class tests whether the other object is a node of the |
| 33 | * same type with structurally isomorphic child subtrees. For nodes with |
| 34 | * list-valued properties, the child nodes within the list are compared in |
| 35 | * order. For nodes with multiple properties, the child nodes are compared |
| 36 | * in the order that most closely corresponds to the lexical reading order |
| 37 | * of the source program. For instance, for a type declaration node, the |
| 38 | * child ordering is: name, superclass, superinterfaces, and body |
| 39 | * declarations. |
| 40 | * </p> |
| 41 | * <p> |
| 42 | * Subclasses may override (extend or reimplement) some or all of the |
| 43 | * <code>match</code> methods in order to define more specialized subtree |
| 44 | * matchers. |
