Class Node_Ext<X>

All Implemented Interfaces:
Direct Known Subclasses:

public abstract class Node_Ext<X> extends Node
Extension to the RDF Data model. This class and any subclasses exist for experimentation and custom extensions. There is no support for them within Apache Jena.

Extension nodes exist so that the machinery of datastructures (graphs, triples) can be used. There is no guarantee that processing Nodes (e.g. writing) will handle extensions.
