[jboss-jira] [JBoss JIRA] Resolved: (JGRP-723) Use Java annotations to automatically set protocol properties

Thu May 8 10:11:59 EDT 2008

     [ http://jira.jboss.com/jira/browse/JGRP-723?page=all ]

Vladimir Blagojevic resolved JGRP-723.
--------------------------------------

    Resolution: Done

Resolved. The algorithm is slightly changed from Bela's outline:

1) Resolve all Protocol fields with @Property annotation and assign values to fields
2) Resolve all Protocol methods with @Property annotation and invoke those methods
3) Invoke Protocol#setProperties to deal with hard to handle scenarios (cannot be handled by steps 1 or 2)

> Currently we use a lot of boiler plate code to read protocol properties specified in configuration file. We can eliminate this unnecessary code by using annotations and a bit of Java reflection that would assign protocol property values to matching Java fields, give warnings for deprecated properties, and so on. We should:
> 1) introduce @ProtocolProperty annotation 
> 2) annotate Protocol fields that are properties 
> 3) test framework
> 4) remove all current boilerplate code
