Moose::Cookbook::Roles::Recipe3 - Applying a role to an object instance
VERSION
version 2.0205
SYNOPSIS
package MyApp::Role::Job::Manager;
use List::Util qw( first );
use Moose::Role;
has 'employees' => (
is => 'rw',
isa => 'ArrayRef[Employee]',
);
sub assign_work {
my $self = shift;
my $work = shift;
my $employee = first { !$_->has_work } @{ $self->employees };
die 'All my employees have work to do!' unless $employee;
$employee->work($work);
}
package main;
my $lisa = Employee->new( name => 'Lisa' );
MyApp::Role::Job::Manager->meta->apply($lisa);
my $homer = Employee->new( name => 'Homer' );
my $bart = Employee->new( name => 'Bart' );
my $marge = Employee->new( name => 'Marge' );
$lisa->employees( [ $homer, $bart, $marge ] );
$lisa->assign_work('mow the lawn');
DESCRIPTION
In this recipe, we show how a role can be applied to an object. In this specific case, we are giving an employee managerial
responsibilities.
Applying a role to an object is simple. The Moose::Meta::Role object provides an "apply" method. This method will do the right thing when
given an object instance.
MyApp::Role::Job::Manager->meta->apply($lisa);
We could also use the "apply_all_roles" function from Moose::Util.
apply_all_roles( $person, MyApp::Role::Job::Manager->meta );
The main advantage of using "apply_all_roles" is that it can be used to apply more than one role at a time.
We could also pass parameters to the role we're applying:
MyApp::Role::Job::Manager->meta->apply(
$lisa,
-alias => { assign_work => 'get_off_your_lazy_behind' },
);
We saw examples of how method exclusion and alias working in roles recipe 2.
CONCLUSION
Applying a role to an object instance is a useful tool for adding behavior to existing objects. In our example, it is effective used to
model a promotion.
It can also be useful as a sort of controlled monkey-patching for existing code, particularly non-Moose code. For example, you could create
a debugging role and apply it to an object at runtime.
