Class FirstReceiverPointToPointRouter

java.lang.Object
  extended byorg.jboss.messaging.core.local.FirstReceiverPointToPointRouter
All Implemented Interfaces:
Distributor, Router

public class FirstReceiverPointToPointRouter
extends java.lang.Object
implements Router

This router deliver the reference to a maximum of one of the router's receivers. It will always favour the first receiver in the internal list of receivers, but will retry the next one (and the next one...) if a previous one does not want to accept the message. If the router has several receivers (e.g. the case of multiple consumers on a queue) then if the consumers are fast then the first receiver will tend to get most or all of the references
