Hello List,
I have a sort() issue that is a bit odd and any input wouls be most
appreciated :)
The code:
use strict;
use warnings;
...
for my $obj(
sort {
$a->value() cmp $b->value()
||
$a->part('Name')->value() cmp $b->part('Name')->value()
}
grep { defined } @objects
) {
...
$a/$b->value() always works since if $a/$b is defined its an object with
a method called value()
$a/$b->part('Name') returns an object that also has a method called
value() or undefined if there is no "Name" part
The sort works perfect for what I need, *except* when
$a/$b->part('Name') does not return an object itself. Then it dies with
"Can't call method value() on undefined value."
So how can I keep my sort() but avoid/work with the "can't call method
on undefined value" error when $a/$b->part('Name') returns undef instead
of an object?
I've put them in valriables depending on defined()ness and done
$name_a cmp $name_b
Which is error free but also doesn't appear to sort it properly :(
TIA!
