Its API looks a lot like L<Moose::Meta::Class>, but internally it implements many things differently. This may change in the future. =head1 INHERITANCE C<Moose::Meta::Role> is a subclass of L<Class::MOP::Module>. =head1 METHODS =head2 Construction =head3 Moose::Meta::Role->initialize($role_name) This method creates a new role object with the provided name. =head3 Moose::Meta::Role->combine( [ $role => { ... } ], [ $role ], ... ) This method accepts a list of array references. Each array reference should contain a role name or L<Moose::Meta::Role> object as its first element. The second element is an optional hash reference. The hash reference can contain C<-excludes> and C<-alias> keys to control how methods are composed from the role. The return value is a new L<Moose::Meta::Role::Composite> that represents the combined roles. =head3 $metarole->composition_class_roles When combining multiple roles using C<combine>, this method is used to obtain a list of role names to be applied to the L<Moose::Meta::Role::Composite> instance returned by C<combine>. The default implementation returns an empty list. Extensions that need to hook into role combination may wrap this method to return additional role names. =head3 Moose::Meta::Role->create($name, %options) This method is identical to the L<Moose::Meta::Class> C<create> method. =head3 Moose::Meta::Role->create_anon_role This method is identical to the L<Moose::Meta::Class> C<create_anon_class> method. =head3 $metarole->is_anon_role Returns true if the role is an anonymous role. =head3 $metarole->consumers Returns a list of names of classes and roles which consume this role. =head2 Role application =head3 $metarole->apply( $thing, @options ) This method applies a role to the given C<$thing>. That can be another L<Moose::Meta::Role>, object, a L<Moose::Meta::Class> object, or a (non-meta) object instance. The options are passed directly to the constructor for the appropriate L<Moose::Meta::Role::Application> subclass. Note that this will apply the role even if the C<$thing> in question already C<does> this role. L<Moose::Util/does_role> is a convenient wrapper for finding out if role application is necessary. =head2 Roles and other roles =head3 $metarole->get_roles This returns an array reference of roles which this role does. This list may include duplicates. =head3 $metarole->calculate_all_roles This returns a I<unique> list of all roles that this role does, and all the roles that its roles do. =head3 $metarole->does_role($role) Given a role I<name> or L<Moose::Meta::Role> object, returns true if this role does the given role. =head3 $metarole->add_role($role) Given a L<Moose::Meta::Role> object, this adds the role to the list of roles that the role does. =head3 $metarole->get_excluded_roles_list Returns a list of role names which this role excludes. =head3 $metarole->excludes_role($role_name) Given a role I<name>, returns true if this role excludes the named role. =head3 $metarole->add_excluded_roles(@role_names) Given one or more role names, adds those roles to the list of excluded roles. =head2 Methods The methods for dealing with a role's methods are all identical in API and behavior to the same methods in L<Class::MOP::Class>. =head3 $metarole->method_metaclass Returns the method metaclass name for the role. This defaults to L<Moose::Meta::Role::Method>. =head3 $metarole->get_method($name) =head3 $metarole->has_method($name) =head3 $metarole->add_method( $name, $body ) =head3 $metarole->get_method_list =head3 $metarole->find_method_by_name($name) These methods are all identical to the methods of the same name in L<Class::MOP::Class> =head2 Attributes As with methods, the methods for dealing with a role's attribute are all identical in API and behavior to the same methods in L<Class::MOP::Class>. However, attributes stored in this class are I<not> stored as objects. Rather, the attribute definition is stored as a hash reference. When a role is composed into a class, this hash reference is passed directly to the metaclass's C<add_attribute> method. This is quite likely to change in the future. =head3 $metarole->get_attribute($attribute_name) =head3 $metarole->has_attribute($attribute_name) =head3 $metarole->get_attribute_list =head3 $metarole->add_attribute($name, %options) =head3 $metarole->remove_attribute($attribute_name) =head2 Overload introspection and creation The methods for dealing with a role's overloads are all identical in API and behavior to the same methods in L<Class::MOP::Class>. =head3 $metarole->is_overloaded =head3 $metarole->get_overloaded_operator($op) =head3 $metarole->has_overloaded_operator($op) =head3 $metarole->get_overload_list =head3 $metarole->get_all_overloaded_operators =head3 $metarole->add_overloaded_operator($op, $impl) =head3 $metarole->remove_overloaded_operator($op) =head2 Required methods =head3 $metarole->get_required_method_list Returns the list of methods required by the role. =head3 $metarole->requires_method($name) Returns true if the role requires the named method. =head3 $metarole->add_required_methods(@names) Adds the named methods to the role's list of required methods. =head3 $metarole->remove_required_methods(@names) Removes the named methods from the role's list of required methods. =head3 $metarole->add_conflicting_method(%params) Instantiate the parameters as a L<Moose::Meta::Role::Method::Conflicting> object, then add it to the required method list. =head2 Method modifiers These methods act like their counterparts in L<Class::MOP::Class> and L<Moose::Meta::Class>. However, method modifiers are simply stored internally, and are not applied until the role itself is applied to a class or object. =head3 $metarole->add_after_method_modifier($method_name, $method) =head3 $metarole->add_around_method_modifier($method_name, $method) =head3 $metarole->add_before_method_modifier($method_name, $method) =head3 $metarole->add_override_method_modifier($method_name, $method) These methods all add an appropriate modifier to the internal list of modifiers. =head3 $metarole->has_after_method_modifiers =head3 $metarole->has_around_method_modifiers =head3 $metarole->has_before_method_modifiers =head3 $metarole->has_override_method_modifier Return true if the role has any modifiers of the given type. =head3 $metarole->get_after_method_modifiers($method_name) =head3 $metarole->get_around_method_modifiers($method_name) =head3 $metarole->get_before_method_modifiers($method_name) Given a method name, returns a list of the appropriate modifiers for that method. =head3 $metarole->get_override_method_modifier($method_name) Given a method name, returns the override method modifier for that method, if it has one. =head2 Introspection =head3 Moose::Meta::Role->meta This will return a L<Class::MOP::Class> instance for this class. =head1 BUGS See L<Moose/BUGS> for details on reporting bugs. =head1 AUTHORS =over 4 =item * Stevan Little <stevan@cpan.org> =item * Dave Rolsky <autarch@urth.org> =item * Jesse Luehrs <doy@cpan.org> =item * Shawn M Moore <sartak@cpan.org> =item * יובל קוג'מן (Yuval Kogman) <nothingmuch@woobling.org> =item * Karen Etheridge <ether@cpan.org> =item * Florian Ragwitz <rafl@debian.org> =item * Hans Dieter Pearcey <hdp@cpan.org> =item * Chris Prather <chris@prather.org> =item * Matt S Trout <mstrout@cpan.org> =back =head1 COPYRIGHT AND LICENSE This software is copyright (c) 2006 by Infinity Interactive, Inc.
