Is it Doug's
if (foo)
bar()
else {
baz();
}
or is it my single line
if (a==null) return 0;
;-)
One of my personal pet peeves is more indentation than necessary for
large blocks of code, rather than just immediately handling the
exception cases and escaping. Example:
void doSomething(MyObj obj) {
if (obj != null) { // at this point, I'm wondering... hmmm, is
there code that executes *after* this huge "if" in the event that obj
is null?
[...]
// same with this one... ya gotta go and try to match up braces
to see if there is code that executes in the opposite case...
// and if it also falls through to execute the obj==null case or
simply returns.
if (some other condition) {
[ tons of code ]
[ tons of code ]
}
}
A much more readable version (regardless of if one likes the
single-line syntax or not):
void doSomething(MyObj obj) {
if (obj==null) return; // immediately obvious handling of the exception case
[...]
if (!some other condition) return; // again, immediately obvious
how the exception case was handled
[ tons of code ]
[ tons of code ]
}
