> In preparation for the planned improvements for JMS config like discussed on the mailing
list the JMS transport should be refactored for readability.
> I have worked myself into the JMS code and at the start had some problems understanding
what happened because of some structures in the code.
> The first thing was JMSTransportBase. Most of the class are methods that do not access
any attributes. These methods could be made static and moved to the JMSUtil class. The method
isDestinationStyleQueue is the only method that needs an attribute. I think it should have
this attribute as a parameter and also be made static and moved to JMSUtils.
> The rest of JMSTransportBase are only holders for attributes that are then accessed from
JMSConduit and JMSDestination directly (even without getters). So I think the whole class
could be dumped and to attributes should be moved to the subclasses. The readability of JMSConduit
and JMSDestination is much better afterwards as the class can be understood in itself.
> The next thing is JMSTransport which is used to feed JMSProviderHub. I think it should
be cut down to the callback method connected and be renamed to JMSOnConnectCallBack. The other
two methods can be added to the parameters of JMSProviderHub. The advantage is that it is
much clearer what JMSProviderHub.connect needs and that connected is a callback that gets
called at the end of connect.
> I have already done the refactorings and will attach a patch with them. Checkstyle, PMD
and surefire show no problems.
