org.eclipse.rdf4j.query.algebra.evaluation.federation.JoinExecutorBase<T>

All Implemented Interfaces:

AutoCloseable, CloseableIteration<T,QueryEvaluationException>, Iteration<T,QueryEvaluationException>

Direct Known Subclasses:

ServiceJoinIterator

@Deprecated
public abstract class JoinExecutorBase<T>
extends JoinExecutorBase<T>

Deprecated.

since 2.3 use JoinExecutorBase

Base class for any join parallel join executor. Note that this class extends LookAheadIteration and thus any implementation of this class is applicable for pipelining when used in a different thread (access to shared variables is synchronized).
