146 | |||||

149 | =pod | ||||
150 | |||||
151 | =head1 NAME | ||||
152 | |||||
153 | Class::MOP::Method - Method Meta Object | ||||
154 | |||||
155 | =head1 VERSION | ||||
156 | |||||
157 | version 2.0602 | ||||
158 | |||||
159 | =head1 DESCRIPTION | ||||
160 | |||||
161 | The Method Protocol is very small, since methods in Perl 5 are just | ||||
162 | subroutines in a specific package. We provide a very basic | ||||
163 | introspection interface. | ||||
164 | |||||
165 | =head1 METHODS | ||||
166 | |||||
167 | =over 4 | ||||
168 | |||||
169 | =item B<< Class::MOP::Method->wrap($code, %options) >> | ||||
170 | |||||
171 | This is the constructor. It accepts a method body in the form of | ||||
172 | either a code reference or a L<Class::MOP::Method> instance, followed | ||||
173 | by a hash of options. | ||||
174 | |||||
175 | The options are: | ||||
176 | |||||
177 | =over 8 | ||||
178 | |||||
179 | =item * name | ||||
180 | |||||
181 | The method name (without a package name). This is required if C<$code> | ||||
182 | is a coderef. | ||||
183 | |||||
184 | =item * package_name | ||||
185 | |||||
186 | The package name for the method. This is required if C<$code> is a | ||||
187 | coderef. | ||||
188 | |||||
189 | =item * associated_metaclass | ||||
190 | |||||
191 | An optional L<Class::MOP::Class> object. This is the metaclass for the | ||||
192 | method's class. | ||||
193 | |||||
194 | =back | ||||
195 | |||||
196 | =item B<< $metamethod->clone(%params) >> | ||||
197 | |||||
198 | This makes a shallow clone of the method object. In particular, | ||||
199 | subroutine reference itself is shared between all clones of a given | ||||
200 | method. | ||||
201 | |||||
202 | When a method is cloned, the original method object will be available | ||||
203 | by calling C<original_method> on the clone. | ||||
204 | |||||
205 | =item B<< $metamethod->body >> | ||||
206 | |||||
207 | This returns a reference to the method's subroutine. | ||||
208 | |||||
209 | =item B<< $metamethod->name >> | ||||
210 | |||||
211 | This returns the method's name | ||||
212 | |||||
213 | =item B<< $metamethod->package_name >> | ||||
214 | |||||
215 | This returns the method's package name. | ||||
216 | |||||
217 | =item B<< $metamethod->fully_qualified_name >> | ||||
218 | |||||
219 | This returns the method's fully qualified name (package name and | ||||
220 | method name). | ||||
221 | |||||
222 | =item B<< $metamethod->associated_metaclass >> | ||||
223 | |||||
224 | This returns the L<Class::MOP::Class> object for the method, if one | ||||
225 | exists. | ||||
226 | |||||
227 | =item B<< $metamethod->original_method >> | ||||
228 | |||||
229 | If this method object was created as a clone of some other method | ||||
230 | object, this returns the object that was cloned. | ||||
231 | |||||
232 | =item B<< $metamethod->original_name >> | ||||
233 | |||||
234 | This returns the method's original name, wherever it was first | ||||
235 | defined. | ||||
236 | |||||
237 | If this method is a clone of a clone (of a clone, etc.), this method | ||||
238 | returns the name from the I<first> method in the chain of clones. | ||||
239 | |||||
240 | =item B<< $metamethod->original_package_name >> | ||||
241 | |||||
242 | This returns the method's original package name, wherever it was first | ||||
243 | defined. | ||||
244 | |||||
245 | If this method is a clone of a clone (of a clone, etc.), this method | ||||
246 | returns the package name from the I<first> method in the chain of | ||||
247 | clones. | ||||
248 | |||||
249 | =item B<< $metamethod->original_fully_qualified_name >> | ||||
250 | |||||
251 | This returns the method's original fully qualified name, wherever it | ||||
252 | was first defined. | ||||
253 | |||||
254 | If this method is a clone of a clone (of a clone, etc.), this method | ||||
255 | returns the fully qualified name from the I<first> method in the chain | ||||
256 | of clones. | ||||
257 | |||||
258 | =item B<< $metamethod->is_stub >> | ||||
259 | |||||
260 | Returns true if the method is just a stub: | ||||
261 | |||||
262 | sub foo; | ||||
263 | |||||
264 | =item B<< $metamethod->attach_to_class($metaclass) >> | ||||
265 | |||||
266 | Given a L<Class::MOP::Class> object, this method sets the associated | ||||
267 | metaclass for the method. This will overwrite any existing associated | ||||
268 | metaclass. | ||||
269 | |||||
270 | =item B<< $metamethod->detach_from_class >> | ||||
271 | |||||
272 | Removes any associated metaclass object for the method. | ||||
273 | |||||
274 | =item B<< $metamethod->execute(...) >> | ||||
275 | |||||
276 | This executes the method. Any arguments provided will be passed on to | ||||
277 | the method itself. | ||||
278 | |||||
279 | =item B<< Class::MOP::Method->meta >> | ||||
280 | |||||
281 | This will return a L<Class::MOP::Class> instance for this class. | ||||
282 | |||||
283 | It should also be noted that L<Class::MOP> will actually bootstrap | ||||
284 | this module by installing a number of attribute meta-objects into its | ||||
285 | metaclass. | ||||
