Talking yesterday at Zurich JUG, describing our IoC, when mentioning Demand/Supply, Bela got an idea of extending that notion with a regexp. Thinking about it, we could have a generic 'transfromer' attribute on the demand/supply element. e.g. | <demand transformer=&quot;org.jboss.ioc.transformer.RegExp&quot;&gt;^[A-Z0-9._%+-]+(a)jboss\.((org)|(com))$&lt;/demand&gt; | | <supply&gt;mc(a)jboss.org&lt;/supply&gt; | | <demand transformer="org.jboss.ioc.transformer.IntLimit">(0,255]</demand> | | <supply transformer="org.jboss.util.propertyeditor.IntegerEditor">128</supply> | Where a demand transformer would create Matcheable, supply transformer would simple be a PropertyEditor. e.g. | public interface Matcheable | { | boolean match(Object other); | } | | for(Map.Entry entry : suppliers.keySet()) | { | if (name instance of Matcheable) | { | Matcheable matcheable = (Matcheable)name; | if (matcheable.match(entry.getKey())) | List<KernelControllerContext> list = entry.getValue(); | if (list != null && list.isEmpty() == false) | return list.get(0); | } | | ... | } | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4099181#...
