Hello to all Apache Commons Developers!
I wish a happy new year and i hope that all your expectations will come
true! I would like to propose a new feature in apache commons... Wouldn't
it
be great if commons api provided a pointer operator (like ref in C#) so as
to pass arguments in functions by references (only for primitive types...)
and these arguments to change values... I would like to hear your thoughts
on this! Thanks for your time!
Do you mean something like
class IntRef{
private int value;
public int getValue()...
public void setValue(int)...
}
?
He mentions "ref" in C#, which works something like this:
public function foo( ref int a ) { a = 42; }
public function bar() {
int b = 0;
foo( ref b );
// b == 42
}
I don't see how Commons could accomplish this goal.
Well, obviously you can't introduce operators with libraries, after all
java ain't perl ;-)
The simplest way to achieve anything resembling output parameters are
mutable flavor of java.lang.Integer &co classes.
