So many other options. The NS > collections are fundamentally flawed that they are concrete.
This is mostly a difference in philosophy. I don't know how Apple implemented the NS* collections in Java though, so my reasoning could be completely wrong. I'm in an interesting position of working on a Java library implementation, WebObjects and with Objective-C/Cocoa at the same time. The only fuel I'm going to add to the fire (and this is a very volatile fuel - it starts religious wars!) is this: Cocoa/WebObject's collection classes describe _intent_, not method. In fact, in Cocoa the underlying implementation actually changes as you use it. Java's collection classes describe the method. They assume that you have a reasonable idea of what you're doing. Personally, I like the Cocoa approach better, it lets me get on with my job without thinking about implementation details. But that's just me :) If you want to know more, try http://ridiculousfish.com/blog/?p=27 -- Phillip Hutchings http://www.sitharus.com/ _______________________________________________ Do not post admin requests to the list.
