Public Member Functions | |
| LocalCopyPropChanger (void) | |
| Node * | at_proc (procNode *, Order) |
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. | |
