Class AnonId

java.lang.Object
org.apache.jena.rdf.model.AnonId
public class AnonId extends Object
System id for an anonymous node.

Blank nodes have identity (.equals tells them apart) but have no web-visible external stable identifier like a URI.

The Jena API has traditionally had AnonId in the RDF API. BlankNodeId is the SPI equivalent and databases that need a persistent identifier across JVM instances use that for blank nodes.

This id is guaranteed to be unique on this machine.
