Class AbstractObjectGraph

java.lang.Object
  wt.fc.WTObject
      wt.graph.AbstractObjectGraph

All Implemented Interfaces:

Externalizable, Serializable, Cloneable, NetFactor, ObjectMappable, Persistable, wt.graph.ObjectGraph, wt.graph.ObjectGraphNode, DisplayIdentification, wt.util.graph.GraphModel, wt.util.graph.GraphNodeModel, NodeExpander, Walker

public abstract class AbstractObjectGraph
extends WTObject
implements wt.graph.ObjectGraph, Externalizable

Provides a value-add "basic" implementation of an object graph abstraction. It wraps the object graph factory, and extends the notion of persistability by being a type of WTObject.

This "basic" implementation can be the customizaton point of where to begin specializing. Or alternatively specialization could start at its supertype the object graph for maximum flexibility.

Supported API: true

Extendable: false
