ServiceJoinIterator

Deprecated.

since 2.3 use JoinExecutorBase

@Deprecated
public abstract class JoinExecutorBase<T>
extends org.eclipse.rdf4j.repository.sparql.federation.JoinExecutorBase<T>

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).
