16 has 'counter' => (
17 traits => ['Counter'],
18 is => 'ro',
19 isa => 'Num',
20 default => 0,

24 reset_counter => 'reset',
25 },
26 );

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 );

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
41 If you don't provide an "isa" value for your attribute, it will default
42 to "Num".
43
45 • set($value)
46
47 Sets the counter to the specified value and returns the new value.
48
49 This method requires a single argument.
50
51 • inc
52
53 • inc($arg)
54
55 Increases the attribute value by the amount of the argument, or by
56 1 if no argument is given. This method returns the new value.
57
58 This method accepts a single argument.
59
60 • dec
61
62 • dec($arg)
63
64 Decreases the attribute value by the amount of the argument, or by
65 1 if no argument is given. This method returns the new value.
66
67 This method accepts a single argument.
68
