Class TrackingTripleIterator

java.lang.Object

org.apache.jena.util.iterator.NiceIterator<T>

org.apache.jena.util.iterator.WrappedIterator<Triple>

org.apache.jena.mem.TrackingTripleIterator

All Implemented Interfaces:

Iterator<Triple>, org.apache.jena.atlas.iterator.IteratorCloseable<Triple>, org.apache.jena.atlas.lib.Closeable, ClosableIterator<Triple>, ExtendedIterator<Triple>

Direct Known Subclasses:

StoreTripleIterator

public class TrackingTripleIterator
extends WrappedIterator<Triple>

A WrappedIterator which remembers the last object next'ed in a protected instance variable, so that subclasses have access to it during .remove. After a call to forEachRemaining(java.util.function.Consumer<? super org.apache.jena.graph.Triple>) current is null. So calling #remove after #forEachRemaining is not supported.
