update_nodes

NodeTree.update_nodes(update_dict: Dict[Union[Node, str], Dict[str, Any]], *, add: bool = False, raise_for_invalid_node: bool = True) → None

Update multiple nodes in the NodeTree.

Similar to update_node() but for multiple elements that are represented as a dict.

Parameters:

• update_dict (Dict[Union[Node, str], Dict[str, Any]]) – Dictionary with node as keys and entries that will be updated as values.

• add (bool) – Flag a non-existing node should be added (default = False).

• raise_for_invalid_node (bool) –

  If set to True, when add is False and the node(s) are invalid/nonexistent, an error is raised.

  Otherwise will issue a warning and continue adding the valid nodes.

  New in version 0.3.4.

Raises:

KeyError – If node does not exist and the add flag is not set

Return type:

None
