Branching off from http://www.jboss.com/index.html?module=bb&op=viewtopic&t=92700 as that thread's a bit wide ranging :) It's nice if individual BuddyLocator, CacheLoader and EvictionPolicy impls can provide POJO config classes; i.e. classes that expose bean properties, rather than config solely via a Properties object. This should be optional; i.e. an impl must be able to configure itself via Properties, but if it has an impl-specific config class that the MC can use, that's good too. This leads to some API changes. I'll use BuddyLocator as an example. First, we add a new BuddyLocatorConfig class. | public static class BuddyLocatorConfig { | | public String getBuddyLocatorClass() {...} | public void setBuddyLocatorClass(String className) {...} | | public Properties getBuddyLocatorProperties() {...} | public void setBuddyLocatorProperties(Properties properties) {...} | | } | Specific BuddyLocator impls can have their own type-specific subclass of this with their own java bean properties, but they must be able to configure themselves via the base superclass w/ its Properties as well. So, BuddyLocator interface becomes: | public interface BuddyLocator | { | public BuddyLocatorConfig getConfig(); | public void init(BuddyLocatorConfig config); | public List locateBuddies(Map buddyPoolMap, List currentMembership, IpAddress dataOwner); | } | Basically init() takes a BuddyLocatorConfig instead of Properties; plus I added a getter for the config. Similar concept would apply to CacheLoader and EvictionPolicy. For CacheLoader, the equivalent to BuddyLocatorConfig already exists with IndividualCacheLoaderConfig; it's just not directly injected into a CacheLoader. So for the CacheLoader interface setConfig() would take IndividualCacheLoaderConfig instead of Properties, plus I'd add a getter for the config as well. Haven't looked int detail at EvictionPolicy, but expect the same concept to apply there. Comments? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3979144#...
