149=head1 NAME
150
151Moose::Meta::Role::Composite - An object to represent the set of roles
152
153=head1 DESCRIPTION
154
155A composite is a role that consists of a set of two or more roles.
156
157The API of a composite role is almost identical to that of a regular
158role.
159
160=head1 INHERITANCE
161
162C<Moose::Meta::Role::Composite> is a subclass of L<Moose::Meta::Role>.
163
164=head2 METHODS
165
166=over 4
167
168=item B<< Moose::Meta::Role::Composite->new(%options) >>
169
170This returns a new composite role object. It accepts the same
171options as its parent class, with a few changes:
172
173=over 8
174
175=item * roles
176
177This option is an array reference containing a list of
178L<Moose::Meta::Role> object. This is a required option.
179
180=item * name
181
182If a name is not given, one is generated from the roles provided.
183
184=item * apply_params(\%role_params)
185
186Creates a new RoleSummation role application with C<%role_params> and applies
187the composite role to it. The RoleSummation role application class used is
188determined by the composite role's C<application_role_summation_class>
189attribute.
190
191=item * reinitialize($metaclass)
192
193Like C<< Class::MOP::Package->reinitialize >>, but doesn't allow passing a
194string with the package name, as there is no real package for composite roles.
