Class BlockingRouter

java.lang.Object

QueueNet.NodeSection

NodeSections.PipeSection

NodeSections.OutputSection

NodeSections.BlockingRouter

public class BlockingRouter
extends OutputSection

This class implements a blocking router, i.e. a router which sends a job inside a region with constraints (the "blocking region"). The destination node has been already defined (the node each job has been redirected from), therefore no routing strategy is required.
