__module__ __qualname__ __slots__r sysstdoutr r r r r r s r c @ s e Zd ZdZdd Zdd ZdS ) NodeVisitora- A base NodeVisitor class for visiting c_ast nodes.
Subclass it and define your own visit_XXX methods, where
XXX is the class name you want to visit with these
methods.
For example:
class ConstantVisitor(NodeVisitor):
def __init__(self):
self.values = []
def visit_Constant(self, node):
self.values.append(node.value)
Creates a list of values of all the constant nodes
encountered below the given node. To use it:
cv = ConstantVisitor()
cv.visit(node)
Notes:
* generic_visit() will be called for AST nodes for which
no visit_XXX method was defined.
* The children of nodes for which a visit_XXX was
defined will not be visited - if you need this, call
generic_visit() on the node.
You can use:
NodeVisitor.generic_visit(self, node)
* Modeled after Python's own AST visiting facilities
(the ast module of Python 3.0)
