pytype.tools.xref.indexer.ScopedVisitor

class documentation

class ScopedVisitor(ast_visitor.BaseVisitor): (source)

Known subclasses: pytype.tools.xref.indexer.IndexVisitor

An AST node visitor that keeps track of scopes and environments. A "scope" is the abstract namespace (represented by a string key that tracks the nested path of namespaces from the module root, e.g. module:class A:f). An "environment" holds data for the current scope. self.envs is not hierarchical, it's just a flat mapping of scope keys to environments.
