SYNOPSIS

10          use Moo;
11          use Sub::HandlesVia;
12          use Types::Standard qw( ArrayRef Str );

14          has food => (
15            is          => 'ro',
16            isa         => ArrayRef[Str],
17            handles_via => 'Array',
18            default     => sub { [] },
19            handles     => {
20              'add_food'    => 'push',
21              'find_food'   => 'grep',
22            },
23          );

DESCRIPTION

35       If you've used Moose's native attribute traits, or MooX::HandlesVia
36       before, you should have a fairly good idea what this does.
37
38       Why re-invent the wheel? Well, this is an implementation that should
39       work okay with Moo, Moose, Mouse, and any other OO toolkit you throw at
40       it.  One ring to rule them all, so to speak.
41
42       For details of how to use it, see the manual.
43
44       Sub::HandlesVia::Manual::WithMoo
45           How to use Sub::HandlesVia with Moo and Moo::Role.
46
47       Sub::HandlesVia::Manual::WithMoose
48           How to use Sub::HandlesVia with Moose and Moose::Role.
49
50       Sub::HandlesVia::Manual::WithMouse
51           How to use Sub::HandlesVia with Mouse and Mouse::Role.
52
53       Sub::HandlesVia::Manual::WithMite
54           How to use Sub::HandlesVia with Mite.
55
56       Sub::HandlesVia::Manual::WithClassTiny
57           How to use Sub::HandlesVia with Class::Tiny.
58
59       Sub::HandlesVia::Manual::WithObjectPad
60           How to use Sub::HandlesVia with Object::Pad classes.
61
62       Sub::HandlesVia::Manual::WithGeneric
63           How to use Sub::HandlesVia with other OO toolkits, and hand-written
64           Perl classes.
65
66       Note: as Sub::HandlesVia needs to detect which toolkit you are using,
67       and often needs to detect whether your package is a class or a role, it
68       needs to be loaded after Moo/Moose/Mouse/etc. Your "use Moo" or "use
69       Moose::Role" or whatever needs to be before your "use Sub::HandlesVia".

103       Sub::HandlesVia::Declare is a helper for declaring Sub::HandlesVia
104       delegations at compile-time, useful for Object::Pad and (to a lesser
105       extent) Class::Tiny.
