Class PersistentQueue

java.lang.Object
  clojure.lang.Obj
      clojure.lang.PersistentQueue

All Implemented Interfaces:

Counted, IHashEq, IMeta, IObj, IPersistentCollection, IPersistentList, IPersistentStack, Seqable, Sequential, Serializable, Iterable, Collection

public class PersistentQueue
extends Obj
implements IPersistentList, Collection, Counted, IHashEq

conses onto rear, peeks/pops from front See Okasaki's Batched Queues This differs in that it uses a PersistentVector as the rear, which is in-order, so no reversing or suspensions required for persistent use
