-1 to making ProxyMap package scope, and only accesible via MapUtils. I think you're reading a little too much into this "contract". The java.util.Map javadocs *recommend* that all *general purpose* Maps have a no-arg, empty-Map constructor and a Map copy-constructor. There are obviously places where this recommendation is going to be violated (consider a Map implementing a fixed mappping). Since we're obviously specifying a specific class when invoking a constructor, I see little problem with having implementation-specific behavior here. Besides, we can't adequately implement ProxyMap(map) as a copy constructor anyway (what's the proxied map type?). > So, SequencedHashMap would be deprecated and removed, and > MapUtils.sequencedMap(Map) added? > > Hen - Rod <http://radio.weblogs.com/0122027/> --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
