NodeTree.update_node(node: Union[Node, str], updates: Dict[str, Any], *, add: bool = False) → None[source]#

Update a node in the NodeTree.

Nodes containing wildcards will be resolved but it is not possible to add new nodes with a node argument containing wildcards.

Parameters:

node (Union[Node, str]) – Node object or string representation.
updates (Dict[str, Any]) – Data that will be updated (overwrites the existing values).
add (bool) – Flag a non-existing node should be added (default = False).

Raises:

KeyError – If node does not exist and the add Flag is not set
ValueError – If the node is passed as a string in form of a relative path and no prefix can be added.

Return type:

None
