Comment on Code Locality by Gazelim

I’ve struggled with this issue too.I haven’t come to any cotrcene conclusions either other than to emphasize that abstraction *costs*.And not only does it cost, but it usually costs *more* than we think it does because the person designing the abstraction is not the same person who has to invest the effort to learn how the abstraction works later on.I think this is one of the main reason why the fcberframeworks fail. When you try to build a framework in a vacuum, separate from a real application that uses the framework, you clearly don’t have a good grasp of the costs of the abstractions you’re creating.So I think whenever we create new abstractions we need to make sure we have very good reasons for doing so, and that we’re not unwittingly creating more trouble than we’re solving.

A pity C isn’t dynamic enough to do what Objective C does – you can throw any object, not just exceptions:

@try {
…
NSException *exception = [NSException exceptionWithName:@"HotTeaException"
reason:@"The tea is too hot" userInfo:nil];
@throw exception;

}
@catch (CustomException *myCustomException) {
…
}
@catch (NSException *myNormalException) {
…
}
@catch (id *anyObjectAtAll) {
…
}
@finally {
…
}

Thank you. I wish I could write an entry a day or even one good one a week. I prefer to write my own, not forward other good entries. Not that there is anything wrong with that blog model, it’s just that I would like to learn how to write well. Preferable in a modest amount of time.

Careful, don’t do this:

int intcmp(unsigned int a, unsigned int b)
{
return (a>b) – (a }
