---------------------------------
Summary: [Java Broker] Configured model objects should have only
one parent
Key: QPID-6028
URL: https://issues.apache.org/jira/browse/QPID-6028
Project: Qpid
Issue Type: Improvement
Components: Java Broker
Reporter: Rob Godfrey
Assignee: Rob Godfrey
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.
