class documentation

class TransformVisitor(NodeVisitor[Node]): (source)

Known subclasses: mypy.checker.TypeTransformVisitor, mypy.test.visitors.TypeAssertTransformVisitor

View In Hierarchy

Transform a semantically analyzed AST (or subtree) to an identical copy. Use the node() method to transform an AST node. Subclass to perform a non-identity transform. Notes: * This can only be used to transform functions or classes, not top-level statements, and/or modules as a whole. * Do not duplicate TypeInfo nodes. This would generally not be desirable. * Only update some name binding cross-references, but only those that refer to Var, Decorator or FuncDef nodes, not those targeting ClassDef or TypeInfo nodes. * Types are not transformed, but you can override type() to also perform type transformation. TODO nested classes and functions have not been tested well enough
