Node object from key (or nodedata)

Is this possible to get a node object from a key (or a nodeData). I only found the reverse way (findNodeDataForKey) in the API or a method to return only the key (getKeyForNodeData).

At the model level, there is Model.findNodeDataForKey.

At the diagram level, there are Diagram.findNodeForKey and Diagram.findNodeForData.

Ok it’s findNodeForKey, I damned 30 minutes I search it on the model and not on the diagram…

Yes, Models don’t know anything about Diagrams or Nodes or Links or any GraphObjects or Tools or CommandHandlers.
