( #3333=superdoc: print w/replies, xml ) Need Help??
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 ./ line xx

So I changed the print statement to:

print ref($employee), "\n";
and got:


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;
