WebIf you get a null value for a nullable field from the server, there are four possibilities: The value is actually null or absent, e.g. user doesn't exist The value is hidden, e.g. user has blocked you (permission error) There was another error fetching the value An error or null value has bubbled up from a Non-Null child WebThe order-zero graph, K 0, is the unique graph having no vertices (hence its order is zero). It follows that K 0 also has no edges.Thus the null graph is a regular graph of degree zero. Some authors exclude K 0 from consideration as a graph (either by definition, or more simply as a matter of convenience). Whether including K 0 as a valid graph is useful …

For some authors, empty graphs and null graphs are different concepts. The null graph is the graph without nodes, while an empty graph is a graph without edges. An empty graph of two vertices is not connected. Regarding the null graph, it of course depends on the definition of connectivity. If a graph is connected if any two vertices can be ...
