210 | =head1 NAME | ||||
211 | |||||
212 | Class::MOP::Method::Wrapped - Method Meta Object for methods with before/after/around modifiers | ||||
213 | |||||
214 | =head1 VERSION | ||||
215 | |||||
216 | version 2.0602 | ||||
217 | |||||
218 | =head1 DESCRIPTION | ||||
219 | |||||
220 | This is a L<Class::MOP::Method> subclass which implements before, | ||||
221 | after, and around method modifiers. | ||||
222 | |||||
223 | =head1 METHODS | ||||
224 | |||||
225 | =head2 Construction | ||||
226 | |||||
227 | =over 4 | ||||
228 | |||||
229 | =item B<< Class::MOP::Method::Wrapped->wrap($metamethod, %options) >> | ||||
230 | |||||
231 | This is the constructor. It accepts a L<Class::MOP::Method> object and | ||||
232 | a hash of options. | ||||
233 | |||||
234 | The options are: | ||||
235 | |||||
236 | =over 8 | ||||
237 | |||||
238 | =item * name | ||||
239 | |||||
240 | The method name (without a package name). This will be taken from the | ||||
241 | provided L<Class::MOP::Method> object if it is not provided. | ||||
242 | |||||
243 | =item * package_name | ||||
244 | |||||
245 | The package name for the method. This will be taken from the provided | ||||
246 | L<Class::MOP::Method> object if it is not provided. | ||||
247 | |||||
248 | =item * associated_metaclass | ||||
249 | |||||
250 | An optional L<Class::MOP::Class> object. This is the metaclass for the | ||||
251 | method's class. | ||||
252 | |||||
253 | =back | ||||
254 | |||||
255 | =item B<< $metamethod->get_original_method >> | ||||
256 | |||||
257 | This returns the L<Class::MOP::Method> object that was passed to the | ||||
258 | constructor. | ||||
259 | |||||
260 | =item B<< $metamethod->add_before_modifier($code) >> | ||||
261 | |||||
262 | =item B<< $metamethod->add_after_modifier($code) >> | ||||
263 | |||||
264 | =item B<< $metamethod->add_around_modifier($code) >> | ||||
265 | |||||
266 | These methods all take a subroutine reference and apply it as a | ||||
267 | modifier to the original method. | ||||
268 | |||||
269 | =item B<< $metamethod->before_modifiers >> | ||||
270 | |||||
271 | =item B<< $metamethod->after_modifiers >> | ||||
272 | |||||
273 | =item B<< $metamethod->around_modifiers >> | ||||
274 | |||||
275 | These methods all return a list of subroutine references which are | ||||
276 | acting as the specified type of modifier. | ||||
277 | |||||
278 | =back | ||||
