java.lang.Object

org.eclipse.rdf4j.common.iteration.AbstractCloseableIteration<E,X>

org.eclipse.rdf4j.common.iteration.LookAheadIteration<E,T>

org.eclipse.rdf4j.common.iteration.QueueIteration<E,QueryEvaluationException>

org.eclipse.rdf4j.query.impl.QueueCursor<E>

org.eclipse.rdf4j.http.client.QueueCursor<E>

All Implemented Interfaces:

AutoCloseable, CloseableIteration<E,QueryEvaluationException>, Iteration<E,QueryEvaluationException>

Direct Known Subclasses:

QueueCursor, QueueCursor

Deprecated.

Use QueueCursor instead

@Deprecated
public class QueueCursor<E>
extends QueueCursor<E>

Makes working with a queue easier by adding the methods QueueIteration.done() and QueueIteration.toss(Exception) and automatically converting the exception into a QueryEvaluationException with an appropriate stack trace.
