Methods defined here:
- add_child(self, label: str, node: ~T = None, graph_kind: Type[~V] = None, **kwargs) -> ~T
- Add an edge between this node (source) and the other node
(destination).
- add_parallel(self, label: str, node: ~T = None, graph_kind: Type[~V] = None, **kwargs) -> ~T
- Add a parallel edge between two nodes. This instance is used as
'node1'.
- add_parent(self, label: str, node: ~T = None, graph_kind: Type[~V] = None, **kwargs) -> ~T
- Add an edge between this node (destination) and the other node
(source).
- to_stream(self, stream: <class 'TextIO'>, **kwargs) -> None
- Write this object to a text stream.
