- Visitors
- ========
-
- To nodes.py, add ``Node.walkabout()``, ``Visitor.leave_*()``, and
- ``GenericVisitor.default_leave()`` methods to catch elements on the
- way out? Here's ``Node.walkabout()``::
-
- def walkabout(self, visitor, ancestry=()):
- """
- Traverse a tree of `Node` objects. Call `visitor`'s
- ``visit_...`` method (upon initial entry) **and** its
- ``leave_...`` method (before exiting).
-
- Parameters:
-
- - `visitor`: A `Visitor` object, containing a ``visit_...``
- and ``leave_...`` method for each `Node` subclass
- encountered.
- - `ancestry`: A list of (parent, index) pairs. `self`'s parent
- is the last entry.
- """
- method = getattr(visitor, 'visit_' + self.__class__.__name__)
- method(self, ancestry)
- children = self.getchildren()
- for i in range(len(children)):
- children[i].walkabout(visitor, ancestry + ((self, i),))
- method = getattr(visitor, 'leave_' + self.__class__.__name__)
- method(self, ancestry)
