| 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 | ||||
