163 |  |  |  |  | =head1 NAME
164 |  |  |  |  |
165 |  |  |  |  | Moose::Meta::Role::Composite - An object to represent the set of roles
166 |  |  |  |  |
167 |  |  |  |  | =head1 VERSION
168 |  |  |  |  |
169 |  |  |  |  | version 2.0602
170 |  |  |  |  |
171 |  |  |  |  | =head1 DESCRIPTION
172 |  |  |  |  |
173 |  |  |  |  | A composite is a role that consists of a set of two or more roles.
174 |  |  |  |  |
175 |  |  |  |  | The API of a composite role is almost identical to that of a regular
176 |  |  |  |  | role.
177 |  |  |  |  |
178 |  |  |  |  | =head1 INHERITANCE
179 |  |  |  |  |
180 |  |  |  |  | C<Moose::Meta::Role::Composite> is a subclass of L<Moose::Meta::Role>.
181 |  |  |  |  |
182 |  |  |  |  | =head2 METHODS
183 |  |  |  |  |
184 |  |  |  |  | =over 4
185 |  |  |  |  |
186 |  |  |  |  | =item B<< Moose::Meta::Role::Composite->new(%options) >>
187 |  |  |  |  |
188 |  |  |  |  | This returns a new composite role object. It accepts the same
189 |  |  |  |  | options as its parent class, with a few changes:
190 |  |  |  |  |
191 |  |  |  |  | =over 8
192 |  |  |  |  |
193 |  |  |  |  | =item * roles
194 |  |  |  |  |
195 |  |  |  |  | This option is an array reference containing a list of
196 |  |  |  |  | L<Moose::Meta::Role> object. This is a required option.
197 |  |  |  |  |
198 |  |  |  |  | =item * name
199 |  |  |  |  |
200 |  |  |  |  | If a name is not given, one is generated from the roles provided.
201 |  |  |  |  |
202 |  |  |  |  | =item * apply_params(\%role_params)
203 |  |  |  |  |
204 |  |  |  |  | Creates a new RoleSummation role application with C<%role_params> and applies
205 |  |  |  |  | the composite role to it. The RoleSummation role application class used is
206 |  |  |  |  | determined by the composite role's C<application_role_summation_class>
207 |  |  |  |  | attribute.
208 |  |  |  |  |
209 |  |  |  |  | =item * reinitialize($metaclass)
210 |  |  |  |  |
211 |  |  |  |  | Like C<< Class::MOP::Package->reinitialize >>, but doesn't allow passing a
212 |  |  |  |  | string with the package name, as there is no real package for composite roles.
