mypy.nodes.TypeInfo

class documentation

class TypeInfo(SymbolNode): (source)

Known subclasses: mypy.nodes.FakeInfo

The type structure of a single class.

Each TypeInfo corresponds one-to-one to a ClassDef, which represents the AST of the class.

In type-theory terms, this is a "type constructor", and if the class is generic then it will be a type constructor of higher kind. Where the class is used in an actual type, it's in the form of an Instance, which amounts to a type application of the tycon to the appropriate number of arguments.

Inherited from Node (via SymbolNode):

Method accept Undocumented

Inherited from Context (via SymbolNode, Node):

Method	`get_column`	Don't use. Use x.column.
Method	`get_line`	Don't use. Use x.line.
Method	`set_line`	If target is a node, pull line (and column) information into this node. If column is specified, this will override any column information coming from a node.
