Detailed Description

Walks the abstract syntax tree and allows modifications of nodes.

The `NodeTransformer` will walk the AST and use the return value of the
visitor functions to replace or remove the old node.  If the return
value of the visitor function is `None` the node will be removed
from the previous location otherwise it's replaced with the return
value.  The return value may be the original node in which case no
replacement takes place.

Member Function Documentation

generic_visit()

Node jinja2.visitor.NodeTransformer.generic_visit	(		self,
		Node	node,
		*t.Any	args,
		**t.Any	kwargs
	)

Called if no explicit visitor function exists for a node.

Reimplemented from jinja2.visitor.NodeVisitor.

Reimplemented in jinja2.optimizer.Optimizer.

visit_list()

t.List[Node] jinja2.visitor.NodeTransformer.visit_list	(		self,
		Node	node,
		*t.Any	args,
		**t.Any	kwargs
	)

As transformers may return lists in some places this method
can be used to enforce a list as return value.
