[Newbies] Re: Beginners Digest, Vol 92, Issue 9

Sat Dec 28 20:32:11 UTC 2013

Hi David,

I was completely mislead by "broadcast". Hardware guy :-))

But whether you use announcements or the ages old dependency mechanism 
(look for changed and update and friends) it means you first will have 
to register to receive the updates, announcements, events ...

Later some object will just iterate over your collection. Usually using 
a framework tends to slow things down a bit but makes things clearer if 
the framework is the right choice for your task.

But go for clarity first then use the profiler then optimise. Sounds 
like I'm repeating Casey here. Well, it's worth repeating :-)

Cheers

Herbert
