[rabbitmq-discuss] To know when a queue is empty from a Java client

Thu Aug 26 14:25:55 BST 2010

The "official" folks should correct me here, but when you declare an existing queue, you get an object back that gives you the message count:

http://www.rabbitmq.com/releases/rabbitmq-java-client/v2.0.0/rabbitmq-java-client-javadoc-2.0.0/com/rabbitmq/client/AMQP.Queue.DeclareOk.html

I don't think there's a way to poll for the message count on a long-running process, though...
