def | get_visitor (self, node) |
def | visit (self, node, *args, **kwargs) |
def | generic_visit (self, node, *args, **kwargs) |
Walks the abstract syntax tree and call visitor functions for every node found. The visitor functions may return values which will be forwarded by the `visit` method. Per default the visitor functions for the nodes are ``'visit_'`` + class name of the node. So a `TryFinally` node visit function would be `visit_TryFinally`. This behavior can be changed by overriding the `get_visitor` function. If no visitor function exists for a node (return value `None`) the `generic_visit` visitor is used instead.
def generic_visit | ( | self, | |
node, | |||
* | args, | ||
** | kwargs | ||
) |
Called if no explicit visitor function exists for a node.
Reimplemented in RootVisitor, NodeTransformer, and Optimizer.
def get_visitor | ( | self, | |
node | |||
) |
Return the visitor function for this node or `None` if no visitor exists for this node. In that case the generic visit function is used instead.
def visit | ( | self, | |
node, | |||
* | args, | ||
** | kwargs | ||
) |
Visit a node.
