Re: Iterating NSSet (was Re: My new framwork)

NSIndexSet internally caches last-accesses, allowing such enumeration (forwards or backwards) to happen very efficiently. The code snippet above should be good enough for most uses. A reason to switch to the get... variant is to avoid the message-sending overhead of the loop, in case that becomes an issue.

That would certainly make a nice addition to the documentation! :) Generally running time for many other methods would, but I'm not the only one who have previously requested this...

On a related note, does NSImage cache the decoded image returned from imageNamed:? I can see that I get the same pointer back, even when I do not retain the result, but I'd rather not rely on caching, if not said so in the docs (but would love to get rid of the 10+ ivars for all the small images used by my custom view plus all the release methods in dealloc).
