Description
The update operation is performed on a Diagram resource. The result of this operation is a Diagram JSON Information object, and the moment the update operation happens for a stored diagram.
It is used to update the diagram resource content; that is, synchronize its content from the network features used to initially generate it, and so reflect any changes that may have impacted those network features into the diagram.
