An NSCharacterSet embodies the concept of "a set of characters." An NSString and NSScanner pair embodies the concept of "how I'm gonna find some characters in a string." The first is a value type, the second an implementation detail. NSCharacterSets are also useful for other things than just finding them in a string or other stream of data. > Seems like a useful one considering the characterSetWithCharactersInString: > method.

I'm confused about what enhancement could be made that would not be highly specific to your application. --Kyle Sluder _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
