1.5.2. Reply-To Addresses and Temporary Queues

There is one minor change to the way the API works over 1.0. This does not affect existing 0-10 use. The change involves the creation of temporary queues (or topics), for example, for retrieving replies in a request-response pattern.

Over 0-10, the Address converts a node name starting with a '#' character by inserting a UUID. This works well for 0-10 where the name is chosen by clients and must be unique. This transformation of the name is done when constructing an Address from a single address string (rather than from its constituent parts). The modified name can then be accessed via Address::getName().

Over 1.0, however, the name for such nodes is determined by the server. In this case the name assigned needs to be communicated back to the application when the attach succeeds. To handle that a new accessor - getAddress() - has been added to both Sender and Receiver.

In order to keep backward compatibility for 0-10, the Address constructor still does the transformation, but applications that want to be able to switch to 1.0 should use these new accessors to obtain the correct address for setting reply-to on any request messages they send. (This new approach will work for both 0-10 and 1.0).
