Public Member Functions |
|
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.
|
|
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.
