NAME

Class::Unique - Create a unique subclass for every instance

VERSION

Version 0.02

SYNOPSIS

package MyClass;

use base 'Class::Unique';

sub foo { print "foo!\n"; }
sub bar { print "bar!\n"; }

...

use MyClass;
my $obj1 = MyClass->new;
my $obj2 = MyClass->new;

my $new_foo = sub { print "new foo!\n"; };
$obj2->install( foo => $new_foo );

$obj1->foo; $obj1->bar;
$obj2->foo; $obj2->bar;

DESCRIPTION

Class::Unique is a base class which provides a constructor and some utility routines for creating objects which instantiate into a unique subclass. If MyClass is a subclass of Class::Unique, and inherrits Class::Unique's constructor, then every object returned by MyClass->new will be blessed into a dynamically created subclass of MyClass. This allows you to modify package data on a per-instance basis.

METHODS

The following methods are inherrited.

new()

Constructor. Returns a hash ref blessed into a new dynamically created package.

install()

Install a new subroutine into an object's class.

$obj->install( subname => $code_ref );

This is really just a shortcut for doing:

my $pkg = ref $obj;
no strict 'refs';
*{ $pkg . '::subname' } = $code_ref;
