NAME Class::Delegation::Simple - Simple delegation for Perl SYNOPSIS package Delegator1; use strict; use warnings 'all'; use Class::Delegation::Simple { send => 'steer', to => 'wheel', as => 'turn', }, { send => 'wipe', to => [qw/ left_wiper right_wiper /] }; sub new { my ($class, %args) = @_; return bless { wheel => Echo->new('wheel'), left_wiper => Echo->new('left_wiper'), right_wiper => Echo->new('right_wiper'), }, $class; }# end new() The "Echo" class: package Echo; sub new { my ($class, $name) = @_; return bless { name => $name }, $class; }# end new() sub AUTOLOAD { my ($s, @args) = @_; our $AUTOLOAD; my ($method) = $AUTOLOAD =~ m/::([^:]+)$/; return "Method '$method'(@args) called on '$s->{name}'!"; }# end AUTOLOAD() sub DESTROY { } The test script: #!perl -w use strict; use warnings 'all'; use Delegator1; my $del = Delegator1->new(); $del->steer('right'); # "Method 'steer'(right) called on 'wheel'!" $del->steer('left'); # "Method 'steer'(left) called on 'wheel'!" $del->wipe('medium'); # "Method 'wipe'(medium) called on 'left_wiper'! Method 'wipe'(medium) called on 'right_wiper'!" DESCRIPTION Class delegation is simply a way to get around some of the problems presented by class inheritance. You can specify that you want some method calls to be handled by one or more attributes of your own choosing. This is much cleaner than constantly hacking out the following: sub steer { my ($s) = shift; $s->{wheel}->steer( @_ ); } sub wipe { my ($s) = shift; my @result = ( $s->{left_wiper}->wipe( @_ ), $s->{right_wiper}->wipe( @_ ) ); return @result; } BUT DOES IT WORK IN MOD_PERL? Yes - it works in mod_perl. Unlike some other Perl Delegation modules on CPAN, this module does not depend on the "INIT" phase to get the work done. This means that it should work just fine in persistent environments such as mod_perl.
