tie::refhash5.18
Tie::RefHash(3pm) Perl Programmers Reference Guide Tie::RefHash(3pm)
NAME
Tie::RefHash - use references as hash keys
SYNOPSIS
require 5.004;
use Tie::RefHash;
tie HASHVARIABLE, 'Tie::RefHash', LIST;
tie HASHVARIABLE, 'Tie::RefHash::Nestable', LIST;
untie HASHVARIABLE;
DESCRIPTION
This module provides the ability to use references as hash keys if you first "tie" the hash variable to this module. Normally, only the
keys of the tied hash itself are preserved as references; to use references as keys in hashes-of-hashes, use Tie::RefHash::Nestable,
included as part of Tie::RefHash.
It is implemented using the standard perl TIEHASH interface. Please see the "tie" entry in perlfunc(1) and perltie(1) for more
information.
The Nestable version works by looking for hash references being stored and converting them to tied hashes so that they too can have
references as keys. This will happen without warning whenever you store a reference to one of your own hashes in the tied hash.
EXAMPLE
use Tie::RefHash;
tie %h, 'Tie::RefHash';
$a = [];
$b = {};
$c = *main;
$d = "gunk";
$e = sub { 'foo' };
%h = ($a => 1, $b => 2, $c => 3, $d => 4, $e => 5);
$a->[0] = 'foo';
$b->{foo} = 'bar';
for (keys %h) {
print ref($_), "
";
}
tie %h, 'Tie::RefHash::Nestable';
$h{$a}->{$b} = 1;
for (keys %h, keys %{$h{$a}}) {
print ref($_), "
";
}
THREAD SUPPORT
Tie::RefHash fully supports threading using the "CLONE" method.
STORABLE SUPPORT
Storable hooks are provided for semantically correct serialization and cloning of tied refhashes.
RELIC SUPPORT
This version of Tie::RefHash seems to no longer work with 5.004. This has not been throughly investigated. Patches welcome ;-)
