Package org.infinispan.persistence.sifs

Class IndexQueue

java.lang.Object

java.util.AbstractCollection<E>

java.util.AbstractQueue<org.infinispan.persistence.sifs.IndexRequest>

org.infinispan.persistence.sifs.IndexQueue

All Implemented Interfaces:

Iterable<org.infinispan.persistence.sifs.IndexRequest>, Collection<org.infinispan.persistence.sifs.IndexRequest>, BlockingQueue<org.infinispan.persistence.sifs.IndexRequest>, Queue<org.infinispan.persistence.sifs.IndexRequest>

public class IndexQueue
extends AbstractQueue<org.infinispan.persistence.sifs.IndexRequest>
implements BlockingQueue<org.infinispan.persistence.sifs.IndexRequest>

Splits the requests into several subqueues according to request.key.hashCode(). If the request has no key, inserts countdown into the request and puts it into all subqueues - the thread that retrieves such element should call countDown() and upon true handle the request (this preserves the FIFO ordering).
