VERSION

version 1.0

SYNOPSIS

use Object::Callback;
use Simple::Log;
use Funky::Log;

my (@listeners);
push @listeners,
    Object::Callback( 'object' => Simple::Log->new( 'file' => '/tmp/junk' ),
                        'method' => 'logline' ),
    Object::Callback( 'object' => Funky::Log->new( 'style' => 'purple with spots' ),
                        'method' => 'jam_this_somewhere' );

while(<>)
{
    $line = $_;
    chomp $line;
    map { $_->callback( $line ); } @listeners;
}

DESCRIPTION

Object::Callback is a simple helper to allow callback to a method on a specific object.

Taking a reference to an object method does not provide the capability to indicate which object this reference should be applied to. Basic perl callback simply handles the code reference and no associated context. To allow for the grouping of both the required object and the method we create an Object::Callback object which contains the required information in a single composite.

COMPATIBILITY

• Object::Callback requires Class::Accessorize::All.
