Class NTripleIterator

java.lang.Object
  org.aksw.commons.collections.SinglePrefetchIterator<com.hp.hpl.jena.graph.Triple>
      org.aksw.commons.reader.NTripleIterator

All Implemented Interfaces:

Iterator<com.hp.hpl.jena.graph.Triple>

public class NTripleIterator
extends SinglePrefetchIterator<com.hp.hpl.jena.graph.Triple>

N-Triple Reader Modified by Claus Stadler: Turned the class into an iterator with returns individual triples from the underlying stream. This allows one to process large streams. TODO Make the code more reusable, such as adding a static NTripleIterator.readFromString method.
