Yeah, that is true.
I wasn't sure if NSConcreteMutableData was a sub-class of
NSMutableData or not (it doesn't have to be).
yes it does
It does? I could be wrong but..
Things come back by way of an id out of init (initWithSomething) and
hence could be anything. As long as it responded to the message I send
it things will be fine.
Basically I can do the following...
id someThing;
someThing = [NSMutableData dataWithBytes:[myString cString]
length:[myString
length]];
[id getBytes:someBuffer];
and...
NSThread stupidBut;
stupidBut = [NSMutableData dataWithBytes:[myString cString]
length:[myString
length]];
[((id) stupidBut) getBytes:someBuffer];
The compiler type checking will not complain about the above.
