Re: [jboss-as7-dev] Descriptions of non-simple attributes

You're right; thanks. And that means one less thing to change on the wiki. :-) On 1/28/11 11:54 AM, Kabir Khan wrote: > With the stuff discussed at [2] doesn't DESCRIPTORS become superfluous?

That is kind of what I wanted to do but didn't really know how to write the description in a nice way. Since there are not many descriptors yet I'd like to clarify the structure and find the best practice. My original thought was that the structure would have to go in the node's description attribute (ATTRIBUTES, KEEPALIVE_TIME, DESCRIPTION below), but it might be nicer to do something like this: >>> >>> node.get(ATTRIBUTES, KEEPALIVE_TIME, DESCRIPTION).set("Used to specify the amount of time that pool threads should be kept running when idle; if not specified, threads will run until the executor is shut down")); >>> node.get(ATTRIBUTES, KEEPALIVE_TIME, TYPE).set(ModelType.OBJECT); >>> node.get(ATTRIBUTES, KEEPALIVE_TIME, REQUIRED).set(false); >>> >>> node.get(ATTRIBUTES, KEEPALIVE_TIME, TIME, DESCRIPTION).set("The time")); >>> node.get(ATTRIBUTES, KEEPALIVE_TIME, TIME, TYPE).set(ModelType.LONG); >>> node.get(ATTRIBUTES, KEEPALIVE_TIME, TIME, REQUIRED).set(false); >>> >>> >>> node.get(ATTRIBUTES, KEEPALIVE_TIME, UNIT, DESCRIPTION).set("The time unit (Seconds, Milliseconds etc.)")); >>> node.get(ATTRIBUTES, KEEPALIVE_TIME, UNIT, TYPE).set(ModelType.STRING); >>> node.get(ATTRIBUTES, KEEPALIVE_TIME, UNIT, REQUIRED).set(false); >>> >>> And if the keepalive-time attribute is optional but if present both time and unit sub-attributes must be specified, I think we would go with something like >>> >>> >>> node.get(ATTRIBUTES, KEEPALIVE_TIME, REQUIRED).set(false); >>> node.get(ATTRIBUTES, KEEPALIVE_TIME, TIME, REQUIRED).set(true); >>> node.get(ATTRIBUTES, KEEPALIVE_TIME, UNIT, REQUIRED).set(true); >>> >>> If it is keepalive-time is required and unit is optional, how about >>> >>> node.get(ATTRIBUTES, KEEPALIVE_TIME, REQUIRED).set(true); >>> node.get(ATTRIBUTES, KEEPALIVE_TIME, TIME, REQUIRED).set(true); >>> node.get(ATTRIBUTES, KEEPALIVE_TIME, UNIT, REQUIRED).set(false); >>> >>> >>> >>> _______________________________________________ >>> jboss-as7-dev mailing list >>> jboss-as7-dev(a)lists.jboss.org >>> https://lists.jboss.org/mailman/listinfo/jboss-as7-dev >> >> >> -- >> Brian Stansberry >> Principal Software Engineer >> JBoss by Red Hat >> _______________________________________________ >> jboss-as7-dev mailing list >> jboss-as7-dev(a)lists.jboss.org >> https://lists.jboss.org/mailman/listinfo/jboss-as7-dev >
