public class GraphObject
extends SharedWrappedGraph
implements ProducingNode

The GraphObject implementation of SharedWrappedGraph is designed to hold loaded instances of file based graph structures in its DataGraph. Using the QueryGrpah it is possible to change the DataGraph even so it is not possible to save the changes. Since the class is used as a resource in the registry the changes will be kept during the execution (the reload function can be used to restore the original data)
