Package org.infinispan.persistence.sifs

Class IndexQueue

  • All Implemented Interfaces:
    java.lang.Iterable<org.infinispan.persistence.sifs.IndexRequest>, java.util.Collection<org.infinispan.persistence.sifs.IndexRequest>, java.util.concurrent.BlockingQueue<org.infinispan.persistence.sifs.IndexRequest>, java.util.Queue<org.infinispan.persistence.sifs.IndexRequest>
    public class IndexQueue
extends java.util.AbstractQueue<org.infinispan.persistence.sifs.IndexRequest>
implements java.util.concurrent.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).
