Class ObjectGraphEdgeFactory

java.lang.Object
  wt.graph.ObjectGraphEdgeFactory

All Implemented Interfaces:

Externalizable, Serializable

public final class ObjectGraphEdgeFactory

extends Object

implements Externalizable

Provides an abstract factory that employs an encoding approach via stream(s) to persist a meta-object's persistent attributes as an XML document. Additionally, this factory employs the Windchill Introspector to faciliate meta-type construction.

Supported API: false

Extendable: false
