Hi all,
I'm just playing with NSStream for the first time, and all the code and
docs I've seen have a switch in the implementation of
stream:handleEvent:, like:
switch(eventCode) {
case NSStreamEventHasBytesAvailable:
...
ex:
<http://developer.apple.com/library/mac/documentation/cocoa/Conceptual/
Streams/Articles/ReadingInputStreams.html#//apple_ref/doc/uid/
20002273-1001882>
Yet the docs also say this:
Stream Event Constants
One or more of these constants may be sent to the delegate as a bit
field in the second parameter of stream:handleEvent:.
typedef enum {
NSStreamEventNone = 0,
NSStreamEventOpenCompleted = 1 << 0,
NSStreamEventHasBytesAvailable = 1 << 1,
NSStreamEventHasSpaceAvailable = 1 << 2,
NSStreamEventErrorOccurred = 1 << 3,
NSStreamEventEndEncountered = 1 << 4
};
If these things can be bitwised ORed, why is all the code out there
'switch'ing? I'm confused.
Thanks,
--
