I
just knew that it would be questioned whether I needed the index or not and that is
precisely why I added the comment at the last minute before posting the question!!!
I use the reference to make the following code more readable. Here is the relevant code in context. endpoints is just a plain array of program paths, the wheels array is in the same order as endpoints array ( FYI is POEtry ;) )
sub endpoint_dead {
my ($kernel, $heap, $wheel_id) = @_[KERNEL, HEAP, ARG0];
$kernel->post('MAIN-Logger', 'alert', "Endpoint managed by wheel $
+wheel_id died\n");
my $self = $heap->{self};
# find the wheel and restart endpoint
foreach(0..$#{@{$self->{endpoints}}}){
my $wheel = $self->{wheels}->[$_];
my $pname = $self->{endpoints}->[$_];
if($wheel->ID == $wheel_id){
[...]
So, as you can see using the index is more elegant than something like:
# find the wheel and restart endpoint
my $i = 0;
foreach(@{$self->{endpoints}){
my $pname = $_;
my $wheel = $self->{wheels}->[$i];
[...]
$i++;
}
Or even more elegant than the for construct in the original question.
