Tie and Tie::Handle

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

I am trying to make an which is basicaly a IO::Socket::INET object with a few extra methods. As far as I can tell I need to use somthing todo with tie, but I have been unable to find much information.

Idealy I would like to beable to create the object using a normal constructor like I normaly would and straight away beable to straight away use like a filehandle

http://www.engelschall.com/~sb/download/pkg/Tie-Handle-3.0.README

from the information at the above url I assumed that the following should work:

package Listen;
require Tie::Handle;

@ISA = qw(Tie::Handle);

use strict;
use warnings;
use IO::Socket::INET;

sub new
{
    #constructor
    my $class = shift;
    my $self = {};
    bless $self;
    $self->tie(new IO::Socket::INET(Listen => 1, LocalPort => 1863, Re
+useAddr => 1));
    return $self;
}

1;
[download]

and then in the main packge:

use listen;

my $test = new Listen;
[download]

However this doesnt seem to work. I have also tried various other things, to no avail.

Any advice would be greatly appriciated,

Alan

I am trying to make an which is basicaly a IO::Socket::INET object with a few extra methods. You could just inherit from IO::Socket::INET and add your additional methods and whatnot. A small example of adding a peerhostport() method follows. `package MyObject; use IO::Socket::INET; @ISA = ("IO::Socket::INET"); sub peerhostport { my $self=shift; my $peerport=$self->peerport; my $peerhost=$self->peerhost; return "$peerhost:$peerport"; } 1; package main; my $foo=MyObject->new(PeerAddr => 'www.perlmonks.org', PeerPort => '80', Proto => 'tcp'); my $string=$foo->peerhostport(); print "string is [$string]\n";` [download] Good luck !

http://www.zeegee.com/code/perl/IO-stringy/docs/IO/WrapTie.pm.html I found this since posting, and it seems exactly what I want and figured it was a good idea to leave this here for anyone else who reads this	[reply]

Are you sure you have Tie::Handle version 3.0? What you get from CPAN is likely version 4. See the COMPATIBILITY section of the perldoc for Tie::Handle for more information. Russ Brainbench 'Most Valuable Professional' for Perl	[reply]
