40 | =head2 METHODS |
41 | |
42 | =head3 action |
43 | |
44 | Add one or more actions. |
45 | |
46 | $c->action( '!foo' => sub { $_[1]->res->output('Foo!') } ); |
47 | |
48 | Get an action's class and coderef. |
49 | |

51 | |
52 | Get a list of available actions. |
53 | |
54 | my @actions = $c->action; |
55 | |
56 | It also automatically calls setup() if needed. |
57 | |
58 | See L<Catalyst::Manual::Intro> for more informations about actions. |
