[rabbitmq-discuss] question on the RpcClient class

[Randall Richard]

I happened to have the source code handy for RpcClient.  Looks like the
reply queue is set up via the setupReplyQueue() method below.

    /**
     * Creates a server-named exclusive autodelete queue to use for
     * receiving replies to RPC requests.
     * @throws IOException if an error is encountered
     * @return the name of the reply queue
     */
    protected String setupReplyQueue() throws IOException {
        return _channel.queueDeclare("", false, true, true,
null).getQueue();
    }

*queueDeclare<http://www.rabbitmq.com/releases/rabbitmq-java-client/v2.4.1/rabbitmq-java-client-javadoc-2.4.1/com/rabbitmq/client/Channel.html#queueDeclare(java.lang.String,
boolean, boolean, boolean, java.util.Map)>*(java.lang.String queue,
boolean durable, boolean exclusive, boolean autoDelete,
java.util.Map<java.lang.String,java.lang.Object> arguments)

So, it looks like it's declared with exclusivity as true.

Regards,

-Randall
