Class MemMessageIdList

java.lang.Object

org.apache.activemq.tool.MemMessageIdList

All Implemented Interfaces:

MessageListener

Direct Known Subclasses:

MemConsumer

public class MemMessageIdList
extends Object
implements MessageListener

A simple container of messages for performing testing and rendezvous style code. You can use this class a MessageListener and then make assertions about how many messages it has received allowing a certain maximum amount of time to ensure that the test does not hang forever.

Also you can chain these instances together with the setParent(MessageListener) method so that you can aggregate the total number of messages consumed across a number of consumers.
