| /** |
| * Instances of the class `GeneralizingASTVisitor` implement an AST visitor that will |
| * recursively visit all of the nodes in an AST structure (like instances of the class |
| * [RecursiveASTVisitor]). In addition, when a node of a specific type is visited not only |
| * will the visit method for that specific type of node be invoked, but additional methods for the |
| * superclasses of that node will also be invoked. For example, using an instance of this class to |
| * visit a [Block] will cause the method [visitBlock] to be invoked but will |
| * also cause the methods [visitStatement] and [visitNode] to be |
| * subsequently invoked. This allows visitors to be written that visit all statements without |
| * needing to override the visit method for each of the specific subclasses of [Statement]. |
| * |
| * Subclasses that override a visit method must either invoke the overridden visit method or |
| * explicitly invoke the more general visit method. Failure to do so will cause the visit methods |
| * for superclasses of the node to not be invoked and will cause the children of the visited node to |
| * not be visited. |
