191 | Class::MOP::Method::Constructor - Method Meta Object for constructors | ||||
192 | |||||
193 | =head1 SYNOPSIS | ||||
194 | |||||
195 | use Class::MOP::Method::Constructor; | ||||
196 | |||||
197 | my $constructor = Class::MOP::Method::Constructor->new( | ||||
198 | metaclass => $metaclass, | ||||

200 | debug => 1, # this is all for now | ||||

202 | ); | ||||

204 | # calling the constructor ... | ||||
205 | $constructor->body->execute($metaclass->name, %params); | ||||
206 | |||||
207 | =head1 DESCRIPTION | ||||
208 | |||||
209 | This is a subclass of C<Class::MOP::Method> which generates | ||||
210 | constructor methods. | ||||
211 | |||||
212 | =head1 METHODS | ||||
213 | |||||
214 | =over 4 | ||||
215 | |||||
216 | =item B<< Class::MOP::Method::Constructor->new(%options) >> | ||||
217 | |||||
218 | This creates a new constructor object. It accepts a hash reference of | ||||
219 | options. | ||||
220 | |||||
221 | =over 8 | ||||
222 | |||||
223 | =item * metaclass | ||||
224 | |||||
225 | This should be a L<Class::MOP::Class> object. It is required. | ||||
226 | |||||
227 | =item * name | ||||
228 | |||||
229 | The method name (without a package name). This is required. | ||||
230 | |||||
231 | =item * package_name | ||||
232 | |||||
233 | The package name for the method. This is required. | ||||
234 | |||||
235 | =item * is_inline | ||||
236 | |||||
237 | This indicates whether or not the constructor should be inlined. This | ||||
238 | defaults to false. | ||||
239 | |||||
240 | =back | ||||
241 | |||||
242 | =item B<< $metamethod->is_inline >> | ||||
243 | |||||
244 | Returns a boolean indicating whether or not the constructor is | ||||
245 | inlined. | ||||
246 | |||||
247 | =item B<< $metamethod->associated_metaclass >> | ||||
248 | |||||
249 | This returns the L<Class::MOP::Class> object for the method. | ||||
