Class ContentValueReference

java.lang.Object
  org.planx.xmlstore.references.ContentValueReference

All Implemented Interfaces:

Serializable, Comparable<ContentValueReference>, Reference, ValueReference

public class ContentValueReference
extends Object
implements ValueReference, Serializable, Comparable<ContentValueReference>

A ValueReference created from a content hash of a Node (currently MD5). This gives a unique location independent ValueReference that can be computed anywhere based on Node data.
