Class AbstractObjectGraphNode

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

All Implemented Interfaces:

Cloneable, DisplayIdentification, Externalizable, GraphNodeModel, NetFactor, NodeExpander, ObjectGraphNode, ObjectMappable, Persistable, Serializable

Direct Known Subclasses:

AbstractObjectGraphNodeTemplate, TransferObjectGraphNode

public abstract class AbstractObjectGraphNode

extends WTObject

implements ObjectGraphNode, Externalizable

Provides a value-add "basic" implementation of an object graph node abstraction. It wraps the object graph node 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 node for maximum flexibility.

Supported API: true

Extendable: false
