Accessors | |
Methods to get and set fields in the class. | |
| Order | order () const |
| Return the order in which Nodes of an AST should be visited. | |
| Depth | depth () const |
| Return which Nodes of an AST should be visited. | |
| bool | delete_old () const |
| Return whether this Changer deletes Nodes which are removed from the AST by "at_" methods. | |
"at_" methods | |
These methods define the functions that should be performed when different classes of Nodes are encountered in the AST. The most specific "at_" method that matches a given Node's class will be called. | |

Detailed Description
Performs a deep copy on part of the AST.This Changer performs a deep copy on the portion of the AST underneath the Node given to it. In addition to copying the structure, it also updates internal links between Nodes in the structure. These links include those between idNode & declNode, tdefNode & the relevant typeNode, callNode & procNode, caseNode & switchNode, gotoNode (including conditiongotoNode) & labelNode, continueNode/breakNode & the container stmtNode, returnNode & procNode, and procNode & the related return_label() & return_decl() in dismantled code.

Entry point for ref_clone_changer. This static method is the entry point for using the ref_clone_changer. The portion of the AST under Node n is copied. Relations between nodes that are both copied is updated by the Changer. For example, if both an idNode and its declNode are copied, then the new idNode will refer to the declNode and vice versa. If nil_bad_links is false, then pointers from copied nodes to a Node outside the subtree are left unchanged. For example, if an idNode is copied, but the original declNode is not copied, then the new idNode will refer to the original declNode. If nil_bad_links is true, then these references will be set to NULL. In this case, an idNode copied without copying the declNode will have a NULL-reference for its decl().

Return which Nodes of an AST should be visited. A value of SubTree specifies that the entire AST should be traversed. A value of NodeOnly specifies that only the root Node in the AST should be visited. |
