Hello,
I'm trying to use Class::Struct, but I'm missing something (probably at a more general level...).
If I run this code I see that if I write a method to override the one created by the Class:Struct module, the attribute name (new_id, in the following) has not the package name prepended. So when I try to access it it is undefined.
Could you please provide me some clue ?
TIA
use strict;
use warnings;
use Data::Dumper;
package Datum;
use Class::Struct;
struct (Datum => {
id => '$',
new_id => '$',
});
sub Datum::new_id {
my $self = shift();
if (@_) {
$self->{new_id} = $_[0] + 1;
}
return $self->{new_id};
}
package Dataset;
use Class::Struct;
struct (Dataset => {
member => '$',
});
sub Dataset::dump_new_id {
my $self = shift();
print "\n\n new_id is undefined\n\n" unless defined ($self->{new_i
+d});
}
package main;
my $dataset = Dataset->new;
my $datum = Datum->new;
$datum->id(3);
$datum->new_id(3);
$dataset->member($datum);
$dataset->dump_new_id;
die Dumper($dataset);
That gives:
new_id is undefined
$VAR1 = bless( {
'Dataset::member' => bless( {
'Datum::id' => 3,
'new_id' => 4,
'Datum::new_id' => unde
+f
}, 'Datum' )
}, 'Dataset' );
