208 | =head1 NAME | |||
209 | ||||
210 | Class::MOP::Method::Accessor - Method Meta Object for accessors | |||
211 | ||||
212 | =head1 SYNOPSIS | |||
213 | ||||
214 | use Class::MOP::Method::Accessor; | |||
215 | ||||
216 | my $reader = Class::MOP::Method::Accessor->new( | |||
217 | attribute => $attribute, | |||
218 | is_inline => 1, | |||
219 | accessor_type => 'reader', | |||
220 | ); | |||
221 | ||||
222 | $reader->body->execute($instance); # call the reader method | |||
223 | ||||
224 | =head1 DESCRIPTION | |||
225 | ||||
226 | This is a subclass of C<Class::MOP::Method> which is used by | |||
227 | C<Class::MOP::Attribute> to generate accessor code. It handles | |||
228 | generation of readers, writers, predicates and clearers. For each type | |||
229 | of method, it can either create a subroutine reference, or actually | |||
230 | inline code by generating a string and C<eval>'ing it. | |||
231 | ||||
232 | =head1 METHODS | |||
233 | ||||
234 | =over 4 | |||
235 | ||||
236 | =item B<< Class::MOP::Method::Accessor->new(%options) >> | |||
237 | ||||
238 | This returns a new C<Class::MOP::Method::Accessor> based on the | |||
239 | C<%options> provided. | |||
240 | ||||
241 | =over 4 | |||
242 | ||||
243 | =item * attribute | |||
244 | ||||
245 | This is the C<Class::MOP::Attribute> for which accessors are being | |||
246 | generated. This option is required. | |||
247 | ||||
248 | =item * accessor_type | |||
249 | ||||
250 | This is a string which should be one of "reader", "writer", | |||
251 | "accessor", "predicate", or "clearer". This is the type of method | |||
252 | being generated. This option is required. | |||
253 | ||||
254 | =item * is_inline | |||
255 | ||||
256 | This indicates whether or not the accessor should be inlined. This | |||
257 | defaults to false. | |||
258 | ||||
259 | =item * name | |||
260 | ||||
261 | The method name (without a package name). This is required. | |||
262 | ||||
263 | =item * package_name | |||
264 | ||||
265 | The package name for the method. This is required. | |||
266 | ||||
267 | =back | |||
268 | ||||
269 | =item B<< $metamethod->accessor_type >> | |||
270 | ||||
271 | Returns the accessor type which was passed to C<new>. | |||
272 | ||||
273 | =item B<< $metamethod->is_inline >> | |||
274 | ||||
275 | Returns a boolean indicating whether or not the accessor is inlined. | |||
276 | ||||
277 | =item B<< $metamethod->associated_attribute >> | |||
278 | ||||
279 | This returns the L<Class::MOP::Attribute> object which was passed to | |||
280 | C<new>. | |||
281 | ||||
282 | =item B<< $metamethod->body >> | |||
283 | ||||
284 | The method itself is I<generated> when the accessor object is | |||
285 | constructed. | |||
