307 |  |  |  |  | =head1 NAME
308 |  |  |  |  |
309 |  |  |  |  | Moose::Meta::TypeConstraint - The Moose Type Constraint metaclass
310 |  |  |  |  |
311 |  |  |  |  | =head1 DESCRIPTION
312 |  |  |  |  |
313 |  |  |  |  | This class represents a single type constraint. Moose's built-in type
314 |  |  |  |  | constraints, as well as constraints you define, are all stored in a
315 |  |  |  |  | L<Moose::Meta::TypeConstraint::Registry> object as objects of this
316 |  |  |  |  | class.
317 |  |  |  |  |
318 |  |  |  |  | =head1 INHERITANCE
319 |  |  |  |  |
320 |  |  |  |  | C<Moose::Meta::TypeConstraint> is a subclass of L<Class::MOP::Object>.
321 |  |  |  |  |
322 |  |  |  |  | =head1 METHODS
323 |  |  |  |  |
324 |  |  |  |  | =over 4
325 |  |  |  |  |
326 |  |  |  |  | =item B<< Moose::Meta::TypeConstraint->new(%options) >>
327 |  |  |  |  |
328 |  |  |  |  | This creates a new type constraint based on the provided C<%options>:
329 |  |  |  |  |
330 |  |  |  |  | =over 8
331 |  |  |  |  |
332 |  |  |  |  | =item * name
333 |  |  |  |  |
334 |  |  |  |  | The constraint name. If a name is not provided, it will be set to
335 |  |  |  |  | "__ANON__".
336 |  |  |  |  |
337 |  |  |  |  | =item * parent
338 |  |  |  |  |
339 |  |  |  |  | A C<Moose::Meta::TypeConstraint> object which is the parent type for
340 |  |  |  |  | the type being created. This is optional.
341 |  |  |  |  |
342 |  |  |  |  | =item * constraint
343 |  |  |  |  |
344 |  |  |  |  | This is the subroutine reference that implements the actual constraint
345 |  |  |  |  | check. This defaults to a subroutine which always returns true.
346 |  |  |  |  |
347 |  |  |  |  | =item * message
348 |  |  |  |  |
349 |  |  |  |  | A subroutine reference which is used to generate an error message when
350 |  |  |  |  | the constraint fails. This is optional.
351 |  |  |  |  |
352 |  |  |  |  | =item * coercion
353 |  |  |  |  |
354 |  |  |  |  | A L<Moose::Meta::TypeCoercion> object representing the coercions to
355 |  |  |  |  | the type. This is optional.
356 |  |  |  |  |
357 |  |  |  |  | =item * optimized
358 |  |  |  |  |
359 |  |  |  |  | This is a variant of the C<constraint> parameter that is somehow
360 |  |  |  |  | optimized. Typically, this means incorporating both the type's
361 |  |  |  |  | constraint and all of its parents' constraints into a single
362 |  |  |  |  | subroutine reference.
363 |  |  |  |  |
364 |  |  |  |  | =back
365 |  |  |  |  |
366 |  |  |  |  | =item B<< $constraint->equals($type_name_or_object) >>
367 |  |  |  |  |
368 |  |  |  |  | Returns true if the supplied name or type object is the same as the
369 |  |  |  |  | current type.
370 |  |  |  |  |
371 |  |  |  |  | =item B<< $constraint->is_subtype_of($type_name_or_object) >>
372 |  |  |  |  |
373 |  |  |  |  | Returns true if the supplied name or type object is a parent of the
374 |  |  |  |  | current type.
375 |  |  |  |  |
376 |  |  |  |  | =item B<< $constraint->is_a_type_of($type_name_or_object) >>
377 |  |  |  |  |
378 |  |  |  |  | Returns true if the given type is the same as the current type, or is
379 |  |  |  |  | a parent of the current type. This is a shortcut for checking
380 |  |  |  |  | C<equals> and C<is_subtype_of>.
381 |  |  |  |  |
382 |  |  |  |  | =item B<< $constraint->coerce($value) >>
383 |  |  |  |  |
384 |  |  |  |  | This will attempt to coerce the value to the type. If the type does
385 |  |  |  |  | have any defined coercions this will throw an error.
386 |  |  |  |  |
387 |  |  |  |  | =item B<< $constraint->check($value) >>
388 |  |  |  |  |
389 |  |  |  |  | Returns true if the given value passes the constraint for the type.
390 |  |  |  |  |
391 |  |  |  |  | =item B<< $constraint->validate($value) >>
392 |  |  |  |  |
393 |  |  |  |  | This is similar to C<check>. However, if the type I<is valid> then the
394 |  |  |  |  | method returns an explicit C<undef>. If the type is not valid, we call
395 |  |  |  |  | C<< $self->get_message($value) >> internally to generate an error
396 |  |  |  |  | message.
397 |  |  |  |  |
398 |  |  |  |  | =item B<< $constraint->assert_valid($value) >>
399 |  |  |  |  |
400 |  |  |  |  | Like C<check> and C<validate>, this method checks whether C<$value> is
401 |  |  |  |  | valid under the constraint. If it is, it will return true. If it is not,
402 |  |  |  |  | an exception will be thrown with the results of
403 |  |  |  |  | C<< $self->get_message($value) >>.
404 |  |  |  |  |
405 |  |  |  |  | =item B<< $constraint->name >>
406 |  |  |  |  |
407 |  |  |  |  | Returns the type's name, as provided to the constructor.
408 |  |  |  |  |
409 |  |  |  |  | =item B<< $constraint->parent >>
410 |  |  |  |  |
411 |  |  |  |  | Returns the type's parent, as provided to the constructor, if any.
412 |  |  |  |  |
413 |  |  |  |  | =item B<< $constraint->has_parent >>
414 |  |  |  |  |
415 |  |  |  |  | Returns true if the type has a parent type.
416 |  |  |  |  |
417 |  |  |  |  | =item B<< $constraint->parents >>
418 |  |  |  |  |
419 |  |  |  |  | A synonym for C<parent>. This is useful for polymorphism with types
420 |  |  |  |  | that can have more than one parent.
421 |  |  |  |  |
422 |  |  |  |  | =item B<< $constraint->constraint >>
423 |  |  |  |  |
424 |  |  |  |  | Returns the type's constraint, as provided to the constructor.
425 |  |  |  |  |
426 |  |  |  |  | =item B<< $constraint->get_message($value) >>
427 |  |  |  |  |
428 |  |  |  |  | This generates a method for the given value. If the type does not have
429 |  |  |  |  | an explicit message, we generate a default message.
430 |  |  |  |  |
431 |  |  |  |  | =item B<< $constraint->has_message >>
432 |  |  |  |  |
433 |  |  |  |  | Returns true if the type has a message.
434 |  |  |  |  |
435 |  |  |  |  | =item B<< $constraint->message >>
436 |  |  |  |  |
437 |  |  |  |  | Returns the type's message as a subroutine reference.
438 |  |  |  |  |
439 |  |  |  |  | =item B<< $constraint->coercion >>
440 |  |  |  |  |
441 |  |  |  |  | Returns the type's L<Moose::Meta::TypeCoercion> object, if one
442 |  |  |  |  | exists.
443 |  |  |  |  |
444 |  |  |  |  | =item B<< $constraint->has_coercion >>
445 |  |  |  |  |
446 |  |  |  |  | Returns true if the type has a coercion.
447 |  |  |  |  |
448 |  |  |  |  | =item B<< $constraint->hand_optimized_type_constraint >>
449 |  |  |  |  |
450 |  |  |  |  | Returns the type's hand optimized constraint, as provided to the
451 |  |  |  |  | constructor via the C<optimized> option.
452 |  |  |  |  |
453 |  |  |  |  | =item B<< $constraint->has_hand_optimized_type_constraint >>
454 |  |  |  |  |
455 |  |  |  |  | Returns true if the type has an optimized constraint.
456 |  |  |  |  |
457 |  |  |  |  | =item B<< $constraint->create_child_type(%options) >>
458 |  |  |  |  |
459 |  |  |  |  | This returns a new type constraint of the same class using the
460 |  |  |  |  | provided C<%options>. The C<parent> option will be the current type.
461 |  |  |  |  |
462 |  |  |  |  | This method exists so that subclasses of this class can override this
463 |  |  |  |  | behavior and change how child types are created.
