Description
The query operation retrieves the attribute values you want for the network features or objects represented in your diagram whether they are aggregated. It is performed on a diagram resource. The result of this operation is a JSON object composed of three arrays—one listing the queried diagram element IDs, another precising whether each is aggregated, and the third one for their set of queried attribute values.

diagram—An array of Diagram Element IDs.Element IDs aggregation—An array of aggregation flags; 1 or 0 that tells whether each diagram element is aggregated.Flags attribute—An array of attribute values corresponding to the requested attributes for each diagram element.Values
