findNodeForData method
Look for a Node or Group corresponding to a model's node data object.
@param {Object} nodedata a JavaScript object matched by reference identity;
use #findNodesByExample if you want to find those Nodes whose data matches an example data object
@return {Node} an existing Node or Group in this Diagram that was
created because its Part.data
was the node data in the Diagram's Model.
This will be null if there is no such part or if it's just a Part or Link.
Implementation
_i3.Node? findNodeForData(_i2.Object nodedata) => _i4.callMethod(
this,
'findNodeForData',
[nodedata],
);
