I am playing with objects and came across a stumbling block.
I have a Person class that appears to be correctly coded, but
I will print it at the bottom of my question just in case.
My problem is in the use of said class.
The Person class has a data field called NAME and method to
set and get it's value called name(). My client code instantiates
a number of Person objects and stores them in a list:
use Person;
use strict;
my @employees = [];
foreach (qw(John Betty Larry Joe Sally Laura Bubba)) {
my $person = Person->new();
$person->name($_);
push @employees, $person;
}
No problems here, now let's say that I want to iterate through
list and print the names of my employees:
foreach my $employee (@employees) {
print $employee->name(), "\n";
}
Uh oh - upon trying to interpret the script, Perl yacks:
Can't call method "name" on unblessed reference at ./foo.pl line xx
So I changed the print statement to:
print ref($employee), "\n";
and got:
ARRAY
Person
Person
Person
Person
Person
Person
Person
Can anyone tell me where did that ARRAY came from?
Here is my Person class as promised: (can anyone say Perltoot?)
package Person;
sub new {
my $proto = shift;
my $class = ref($proto) || $proto;
my $self = {};
$self->{NAME} = undef;
bless ($self, $class);
return $self;
}
sub name {
my $self = shift;
if (@_) { $self->{NAME} = shift }
return $self->{NAME};
}
1;
Thanks!
