public class SortedMailboxReceiveOperator
extends BaseMailboxReceiveOperator

This SortedMailboxReceiveOperator receives data from a ReceivingMailbox and serve it out from the MultiStageOperator.getNextBlock()()} API in a sorted manner. TODO: Once sorting on the MailboxSendOperator is available, modify this to use a k-way merge instead of resorting via the PriorityQueue.
