[jira] [Commented] (QPID-6028) [Java Broker] Configured model

[ https://svn.apache.org/r1775689 ]
QPID-6028: [Java Broker] Eliminate model objects with multiple parents.
- Binding no longer a model object.
- Exchange have bindings that are associated with Destinations (routing supports queue at the moment)
- Consumer now has a single parent Queue.
- Bindings refactored

> Key: QPID-6028
> URL: https://issues.apache.org/jira/browse/QPID-6028
> Project: Qpid
> Issue Type: Improvement
> Components: Java Broker
> Reporter: Rob Godfrey
> Assignee: Keith Wall
> Fix For: qpid-java-7.0.0
>
>
> Currently it is possible for a configured object to be defined as having multiple parents (of different classes)
> Thus a binding has a "queue" parent and an "exchange" parent, a consumer has a "session" parent and a "queue" parent, a virtualhostalias has a "port" parent and a virtialhost parent.
> This design should be changed.
> h5. Bindings
> Bindings should have a single exchange parent with the queue being an attribute (note that this probably also requires adding binding-key as an attribute and setting the name to queue/binding-key or some such. Exchange-wide validation on the binding-key will be required)
> h5. Consumers
> Since in AMQP 1.0 a link endpoint may outlive the session that created it, it makes sense for the parent of the Consumer to be the Queue. The Session will be a (derived) attribute of the Consumer.
> h5. VirtualhostAliases
> The primary parent of the virtualhostalias should be the (amqp) port. The virtualHost should be an attribute. On creating a VirtualHost we should offer to create an alias for the virtual host on all existing ports with the host name as the alias. On creating a port we should offer to create aliases for each of the existing virtualhosts.
