You can do that with AUTOLOAD, for example with:
package MyAutoloadDemo;
use strict;
use warnings;
use Carp;
our $AUTOLOAD;
sub new {
my $class = shift;
my $self = {};
$self->{'data'}->{'name'} = 'spiros';
$self->{'data'}->{'address'} = 'london';
bless $self, $class;
return $self;
}
sub AUTOLOAD {
my $self = shift;
my $type = ref $self;
my $name = $AUTOLOAD;
$name =~ s/.*://; # strip fully-qualified portion
if (!exists $self->{data}->{$name} ) {
croak "Can't access $name field in class $type";
}
return $self->{data}->{$name};
}
1;
use MyAutoloadDemo;
my $demo = MyAutoloadDemo->new();
warn $demo->name;
warn $demo->address;
warn $demo->unknown;
This prints:
spiros at test.pl line 4.
london at test.pl line 5.
Can't access unknown field in class MyAutoloadDemo at test.pl line 6
But you probably want something from CPAN's Class:: namespace, eg.
Class::MethodMaker,
Class::Accessor,
Class::Std, ..
