15 | This class represents a Catalyst Action. You can access the object for the |
b2ddf6d7 |
16 | currently dispatched action via $c->action. See the L<Catalyst::Dispatcher> |
17 | for more information on how actions are dispatched. Actions are defined in |
18 | L<Catalyst::Controller> subclasses. |

b5ecfcf0 |
483 | =head2 attributes |
fbcc39ad |
484 | |
4ab87e27 |
485 | The sub attributes that are set for this action, like Local, Path, Private |
b2ddf6d7 |
486 | and so on. This determines how the action is dispatched to. |
4ab87e27 |
487 | |
b5ecfcf0 |
488 | =head2 class |
b96f127f |
489 | |
4d38cb07 |
490 | Returns the name of the component where this action is defined. |
f9818250 |
491 | Derived by calling the L<catalyst_component_name|Catalyst::Component/catalyst_component_name> |
fb0c5b21 |
492 | method on each component. |
4ab87e27 |
493 | |
b5ecfcf0 |
494 | =head2 code |
11bd4e3e |
495 | |
b2ddf6d7 |
496 | Returns a code reference to this action. |
4ab87e27 |
497 | |
b8f669f3 |
498 | =head2 dispatch( $c ) |
4ab87e27 |
499 | |
18a9655c |
500 | Dispatch this action against a context. |
fbcc39ad |
501 | |
b8f669f3 |
502 | =head2 execute( $controller, $c, @args ) |
503 | |
504 | Execute this action's coderef against a given controller with a given |
505 | context and arguments |
506 | |
649fd1fa |
507 | =head2 match( $c ) |
4ab87e27 |
508 | |
649fd1fa |
509 | Check Args attribute, and makes sure number of args matches the setting. |
b2ddf6d7 |
510 | Always returns true if Args is omitted. |
4082e678 |
511 | |
760d121e |
512 | =head2 match_captures ($c, $captures) |
513 | |
514 | Can be implemented by action class and action role authors. If the method |
515 | exists, then it will be called with the request context and an array reference |
516 | of the captures for this action. |
517 | |
518 | Returning true from this method causes the chain match to continue, returning |
519 | makes the chain not match (and alternate, less preferred chains will be attempted). |
520 | |
ec4d7259 |
521 | =head2 match_captures_constraints ($c, \@captures); |
522 | |
523 | Does the \@captures given match any constraints (if any constraints exist). Returns |
524 | true if you ask but there are no constraints. |
525 | |
c1192f1e |
526 | =head2 match_args($c, $args) |
527 | |
75ce30d0 |
528 | Does the Args match or not? |

529 | |
6f0b85d2 |
530 | =head2 resolve_type_constraint |
531 | |
79fb8f95 |
532 | Tries to find a type constraint if you have on on a type constrained method. |

533 | |
91955398 |
534 | =head2 compare |
535 | |
cbe555e8 |
536 | Compares 2 actions based on the value of the C<Args> attribute, with no C<Args> |
537 | having the highest precedence. |
91955398 |
538 | |
b5ecfcf0 |
539 | =head2 namespace |
fbcc39ad |
540 | |
4ab87e27 |
541 | Returns the private namespace this action lives in. |

543 | =head2 reverse |
6b239949 |
544 | |
4ab87e27 |
545 | Returns the private path for this action. |
546 | |
009b5b23 |
547 | =head2 private_path |
548 | |
549 | Returns absolute private path for this action. Unlike C<reverse>, the |
550 | C<private_path> of an action is always suitable for passing to C<forward>. |
551 | |
b5ecfcf0 |
552 | =head2 name |
fbcc39ad |
553 | |
18a9655c |
554 | Returns the sub name of this action. |

555 | |
0cff119a |
556 | =head2 number_of_args |
557 | |
d4e8996f |
558 | Returns the number of args this action expects. This is 0 if the action doesn't |
559 | take any arguments and undef if it will take any number of arguments. |
560 | |
561 | =head2 normalized_arg_number |
562 | |
5dd46e24 |
563 | The number of arguments (starting with zero) that the current action defines, or |
564 | undefined if there is not defined number of args (which is later treated as, " |
565 | as many arguments as you like"). |
566 | |
567 | =head2 comparable_arg_number |
568 | |
d4e8996f |
569 | For the purposes of comparison we normalize 'number_of_args' so that if it is |
570 | undef we mean ~0 (as many args are we can think of). |
0cff119a |
571 | |
572 | =head2 number_of_captures |
573 | |
574 | Returns the number of captures this action expects for L<Chained|Catalyst::DispatchType::Chained> actions. |
