Hi All:
I do like using NullArgumentException, but I find writing this over and over
tedious:
if (arg == null) {
thrown new NullArgumentException(argName);
}
something(arg);
How about this instead:
NullArgumentException.check(arg, argName);
something(arg);
or:
something(NullArgumentException.check(arg, argName));
Depending on the style you like.
Where check is:
public static <T> T check(T arg, String argName) {
if (arg == null) {
throw new NullArgumentException(argName);
}
return arg;
}
Yes, you are pushing the argName on the stack (or passing it in a register)
and that is extra work, but you do not have to use the new method then ;)
?
