public class GraphNode : DisposableWrapper;
This .NET class wraps the AcDbGraphNode ObjectARX class.
This class provides a generic graph node implementation. One other class is also involved in the graph mechanism: Graph.
Detection for circular references is done by internally creating a duplicate set of references in each node, then trimming away all leaf nodes which terminate without circularity. If any nodes remain in the duplicate graph, those nodes exist in a cycle. Graph.FindCycles() is used to set up the internal cycle information and enable several query methods to return information about any cycles found.
