All Implemented Interfaces:

MetaObject, StandardBean

public class GraphMetaObject
extends AbstractMetaObject

Presents a MetaObject view of a node in a graph. A map is given that tells the meta-object how to traverse the graph to find the property values. Each map entry maps a property name to an EdgeDefinition object that can be used to view the graph. Any properties not found in the map will be passed on to the node itself if it is a meta-object.
