| 224 | ||||
| 225 | Class::MOP::Instance - Instance Meta Object | |||
| 226 | ||||
| 227 | =head1 DESCRIPTION | |||
| 228 | ||||
| 229 | The Instance Protocol controls the creation of object instances, and | |||
| 230 | the storage of attribute values in those instances. | |||
| 231 | ||||
| 232 | Using this API directly in your own code violates encapsulation, and | |||
| 233 | we recommend that you use the appropriate APIs in L<Class::MOP::Class> | |||
| 234 | and L<Class::MOP::Attribute> instead. Those APIs in turn call the | |||
| 235 | methods in this class as appropriate. | |||
| 236 | ||||
| 237 | This class also participates in generating inlined code by providing | |||
| 238 | snippets of code to access an object instance. | |||
| 239 | ||||
| 240 | =head1 METHODS | |||
| 241 | ||||
| 242 | =head2 Object construction | |||
| 243 | ||||
| 244 | =over 4 | |||
| 245 | ||||
| 246 | =item B<< Class::MOP::Instance->new(%options) >> | |||
| 247 | ||||
| 248 | This method creates a new meta-instance object. | |||
| 249 | ||||
| 250 | It accepts the following keys in C<%options>: | |||
| 251 | ||||
| 252 | =over 8 | |||
| 253 | ||||
| 254 | =item * associated_metaclass | |||
| 255 | ||||
| 256 | The L<Class::MOP::Class> object for which instances will be created. | |||
| 257 | ||||
| 258 | =item * attributes | |||
| 259 | ||||
| 260 | An array reference of L<Class::MOP::Attribute> objects. These are the | |||
| 261 | attributes which can be stored in each instance. | |||
| 262 | ||||

| 272 | ||||
| 273 | This method returns a reference blessed into the associated | |||
| 274 | metaclass's class. | |||
| 275 | ||||
| 276 | The default is to use a hash reference. Subclasses can override this. | |||
| 277 | ||||
| 278 | =item B<< $metainstance->clone_instance($instance) >> | |||
| 279 | ||||

| 295 | ||||
| 296 | This returns a list of slot names stored in object instances. In | |||
| 297 | almost all cases, slot names correspond directly attribute names. | |||
| 298 | ||||
| 299 | =item B<< $metainstance->is_valid_slot($slot_name) >> | |||
| 300 | ||||
| 301 | This will return true if C<$slot_name> is a valid slot name. | |||
| 302 | ||||
| 303 | =item B<< $metainstance->get_all_attributes >> | |||

| 311 | ||||
| 312 | It's important to understand that the meta-instance object is a | |||
| 313 | different entity from the actual instances it creates. For this | |||
| 314 | reason, any operations on the C<$instance_structure> always require | |||
| 315 | that the object instance be passed to the method. | |||

| 340 | from the method name. | |||

| 346 | =over 4 | |||
| 347 | ||||
| 348 | =item B<< $metainstance->is_inlinable >> | |||
| 349 | ||||
| 350 | This is a boolean that indicates whether or not slot access operations | |||
| 351 | can be inlined. By default it is true, but subclasses can override | |||
| 352 | this. | |||
| 353 | ||||
| 354 | =item B<< $metainstance->inline_create_instance($class_variable) >> | |||
| 355 | ||||
| 356 | This method expects a string that, I<when inlined>, will become a | |||
| 357 | class name. This would literally be something like C<'$class'>, not an | |||
| 358 | actual class name. | |||
| 359 | ||||
| 360 | It returns a snippet of code that creates a new object for the | |||
| 361 | class. This is something like C< bless {}, $class_name >. | |||
| 362 | ||||
| 363 | =item B<< $metainstance->inline_slot_access($instance_variable, $slot_name) >> | |||

| 376 | ||||
| 377 | =item B<< $metainstance->inline_strengthen_slot_value($instance_variable, $slot_name) >> | |||
| 378 | ||||
| 379 | These methods all expect two arguments. The first is the name of a | |||
| 380 | variable, than when inlined, will represent the object | |||
| 381 | instance. Typically this will be a literal string like C<'$_[0]'>. | |||
| 382 | ||||
| 383 | The second argument is a slot name. | |||
| 384 | ||||
| 385 | The method returns a snippet of code that, when inlined, performs some | |||
| 386 | operation on the instance. | |||
| 387 | ||||
| 388 | =item B<< $metainstance->inline_rebless_instance_structure($instance_variable, $class_variable) >> | |||
| 389 | ||||
| 390 | This takes the name of a variable that will, when inlined, represent the object | |||
| 391 | instance, and the name of a variable that will represent the class to rebless | |||
| 392 | into, and returns code to rebless an instance into a class. | |||

| 402 | This will return a L<Class::MOP::Class> instance for this class. | |||
| 403 | ||||
| 404 | It should also be noted that L<Class::MOP> will actually bootstrap | |||
| 405 | this module by installing a number of attribute meta-objects into its | |||
| 406 | metaclass. | |||
