12
14 This class represents a Catalyst Action. You can access the object for
15 the currently dispatched action via $c->action. See the
16 Catalyst::Dispatcher for more information on how actions are
17 dispatched. Actions are defined in Catalyst::Controller subclasses.
18
20 attributes
21 The sub attributes that are set for this action, like Local, Path,
22 Private and so on. This determines how the action is dispatched to.
23
24 class
25 Returns the name of the component where this action is defined.
26 Derived by calling the catalyst_component_name method on each
27 component.
28
29 code
30 Returns a code reference to this action.
31
32 dispatch( $c )
33 Dispatch this action against a context.
34
35 execute( $controller, $c, @args )
36 Execute this action's coderef against a given controller with a given
37 context and arguments
38
39 match( $c )
40 Check Args attribute, and makes sure number of args matches the
41 setting. Always returns true if Args is omitted.
42
43 match_captures ($c, $captures)
44 Can be implemented by action class and action role authors. If the
45 method exists, then it will be called with the request context and an
46 array reference of the captures for this action.
47
48 Returning true from this method causes the chain match to continue,
49 returning makes the chain not match (and alternate, less preferred
50 chains will be attempted).
51
52 match_captures_constraints ($c, \@captures);
53 Does the \@captures given match any constraints (if any constraints
54 exist). Returns true if you ask but there are no constraints.
55
56 match_args($c, $args)
57 Does the Args match or not?
58
59 resolve_type_constraint
60 Tries to find a type constraint if you have on on a type constrained
61 method.
62
63 compare
64 Compares 2 actions based on the value of the "Args" attribute, with no
65 "Args" having the highest precedence.
66
67 namespace
68 Returns the private namespace this action lives in.
69
70 reverse
71 Returns the private path for this action.
72
73 private_path
74 Returns absolute private path for this action. Unlike "reverse", the
75 "private_path" of an action is always suitable for passing to
76 "forward".
77
78 name
79 Returns the sub name of this action.
80
81 number_of_args
82 Returns the number of args this action expects. This is 0 if the action
83 doesn't take any arguments and undef if it will take any number of
84 arguments.
85
86 normalized_arg_number
87 The number of arguments (starting with zero) that the current action
88 defines, or undefined if there is not defined number of args (which is
89 later treated as, " as many arguments as you like").
90
91 comparable_arg_number
92 For the purposes of comparison we normalize 'number_of_args' so that if
93 it is undef we mean ~0 (as many args are we can think of).
94
95 number_of_captures
96 Returns the number of captures this action expects for Chained actions.
97
98 list_extra_info
99 A HashRef of key-values that an action can provide to a debugging
100 screen
101
102 scheme
103 Any defined scheme for the action
104
105 meta
106 Provided by Moose.
