And calling the return value from -name "autoreleased" would imply
the second implementation, which might not be the case.
Indeed.
Out of curiosity, is this what the docs mean in the few places they
say a return value is autoreleased, or is that just someone making
the same old mistake?
I don't know for each individual case, but I suspect it's more likely
to be the same old mistake. Each really ought to be investigated.
Moreover, saying that an object is "autoreleased" also implies the
overhead of adding it to an autorelease pool, suggesting that it
may be more expensive to retrieve the object than is actually the
case.
Okay... I thought I had a reasonable suggestion but I see it was a
pretty crappy one. I'll see if I can get comfortable with the
ownership terminology.
Looking at your earlier reply, I take the point about "ownership" --
if someone can come up with something better, that would be great!
