SYNOPSIS

13         package MyHomePage;
14         use Moose;
15
16         has 'counter' => (
17             traits  => ['Counter'],
18             is      => 'ro',
19             isa     => 'Num',
20             default => 0,
21             handles => {
22                 inc_counter   => 'inc',
23                 dec_counter   => 'dec',
24                 reset_counter => 'reset',
25             },
26         );
27
28         my $page = MyHomePage->new();
29         $page->inc_counter;    # same as $page->counter( $page->counter + 1 );
30         $page->dec_counter;    # same as $page->counter( $page->counter - 1 );
31
32         my $count_by_twos = 2;
33         $page->inc_counter($count_by_twos);

DESCRIPTION

36       This trait provides native delegation methods for counters. A counter
37       can be any sort of number (integer or not). The delegation methods
38       allow you to increment, decrement, or reset the value.
39

DEFAULT TYPE

41       If you don't provide an "isa" value for your attribute, it will default
42       to "Num".
43
