Accessing hash in blessed object

on Oct 13, 2014 at 17:48 UTC ( #1103653=perlquestion: print w/replies, xml ) Need Help??

glenn has asked for the wisdom of the Perl Monks concerning the following question:

I have a feeling i'm going to feel stupid when I see the answer, however I have tried and searched to no avail. I have created a lib and blessed an object which contains a hashref. All was going well until I tried to use it. I have left out... most but this is the important stuff. The buffer hash is used to hold line by line input until an XML beginning and end is matched for each client system.

Found stupid answer... nested hashref is not allowed with shared.

I created a meditation, RFC: Bi-directional multi-client non-blocking TCP server/client, based on the working code which spawned this question.

use Data::Dumper; use Carp; use threads; sub new { my $class = shift; croak "Port number required" unless(@_); my $port :shared = shift; my %buffer :shared; my %self :shared = ( 'port' => \$port, 'buffer' => \%buffer, ); bless(\%self, $class); threads->create('_RXserver', \%self)->detach(); return \%self; } sub _RXserver { local *__ANON__ = '_RXserver'; my $self = shift; # $self->{'buffer'}->{'172.0.0.1:40000'} = 'value'; #works $self->{'buffer'}->{'172.0.0.1:40000'}->{'read'} = 'value'; #fails print Dumper $self; }

    I'm a bit puzzled about what you are doing here, but let me throw this out there and maybe it'll help:

    package MyThreadSpool; use Carp; use threads; sub new { shift; croak "Port number required" unless(@_); my $port :shared = shift; my %buffer :shared; my $self = { port => $port, buffer => \%buffer } bless $self,"MyThreadSpool"; return $self }
    and in some code coming to a workstation/laptop near you:
    #!/usr/bin/perl -w use strict; use MyThreadSpool; my $obj = MyThreadSpool->new(8080,my %buffer); # and so now print $obj->{port}.... etc etc etc
    Is this something approximating what you are trying to do?

    print Dumper $self;

    What's the Dumper output?

    UPDATE: I'm asking, because it seems to work for me:

    $VAR1 = bless( { 'port' => \'9999', 'buffer' => { '172.0.0.1:40000' => { 'read' => 'value +' } } }, 'main' );
