NAME

6       Sub::HandlesVia::Declare - declare delegations at compile-time
7

SYNOPSIS

9        use Sub::HandlesVia::Declare( $attr, $via => %delegations );
10
11       This is roughly equivalent to the following:
12
13        use Sub::HandlesVia qw(delegations);
14
15        BEGIN {
16          delegations(
17            attribute    => $attr,
18            handles_via  => $via,
19            handles      => \%delegations,
20          );
21        };
22
23       Except it doesn't import the "delegations" function into your
24       namespace.
25

DESCRIPTION

27       Useful for Object::Pad and kind of nice for Class::Tiny. Basically any
28       class builder than does its stuff at compile time.
29
30   Object::Pad
31        use Object::Pad;
32
33        class Kitchen {
34          has @foods;
35          use Sub::HandlesVia::Declare '@foods', Array => (
36            all_foods => 'all',
37            add_food  => 'push',
38          );
39        }
40
41       If an attribute begins with a '@' or '%', $via can be omitted.
42
43        use Object::Pad;
44
45        class Kitchen {
46          has @foods;
47          use Sub::HandlesVia::Declare '@foods', (
48            all_foods => 'all',
49            add_food  => 'push',
50          );
51        }
52
53   Class::Tiny
54        package Kitchen;
55        use Class::Tiny {
56          foods  => sub { [] },
57          drinks => sub { [ 'water' ] },
58        };
59        use Sub::HandlesVia::Declare 'foods', Array => (
60          all_foods  => 'all',
61          add_food   => 'push',
62        );
63        use Sub::HandlesVia::Declare 'drinks', Array => (
64          all_drinks => 'all',
65          add_drink  => 'push',
66        );
