Greetings!
I have a class that contains a member that is an array. I have a
method of the class that gets me a reference to the array. I can print
out the contents of the array. But I can't find out how many items are
in it! What is going on here? There's something simple I'm missing.
Here's the code that retrieves the reference to the array, with a bunch
of print statements in it to try to figure out if I know what I'm doing
or not:
sub GetCrewList
{
my $self = shift;
print "Getting crew list<br>";
my $crewListRef = $self->{'crew'};
my @crewArray = @$crewListRef;
print "Crew: @$crewListRef<br>";
print "CrewArray: @crewArray<br>";
my $crewArrayCount = scalar(@crewArray);
my $crewCount = $#crewArray;
print "Crew count: $crewCount<br>";
print "Crew array count: $crewArrayCount";
return $self->{'crew'};
}
Here's the output of the print statements:
Getting crew list
Crew: 2.14.2003,Wine Train - BX,17:00,Person 1,Person 2,Person 3,Person
4,Person 5,Person 6,Person 7,Person 8,Person 9,Person 10,Person
11,Person 12,Person 13,Person 14
CrewArray: 2.14.2003,Wine Train - BX,17:00,Person 1,Person 2,Person
3,Person 4,Person 5,Person 6,Person 7,Person 8,Person 9,Person
10,Person 11,Person 12,Person 13,Person 14
Crew count: 0
Crew array count: 1The first train has 1 crewpeople.
The local array has 1 people.
The only thing I can think of is that maybe I have managed to create an
array that contains only one thing, a reference to another array. But
then the "print @crewListRef" statement wouldn't have had valid syntax,
would it?
RobR, completely mystified.
