DESCRIPTION

30       This module provides a simple counter attribute, which can be
31       incremented and decremeneted.
32
33       If your attribute definition does not include any of is, isa, default
34       or provides but does use the "Counter" metaclass, then this module
35       applies defaults as in the "SYNOPSIS" above. This allows for a very
36       basic counter definition:
37
38         has 'foo' => (metaclass => 'Counter');
39         $obj->inc_foo;
40

METHODS

42       meta
43       method_provider
44       has_method_provider
45       helper_type
46       process_options_for_provides
47           Run before its superclass method.
48
49       check_provides_values
50           Run after its superclass method.
51

PROVIDED METHODS

53       It is important to note that all those methods do in place modification
54       of the value stored in the attribute.
55
56       set Set the counter to the specified value.
57
58       inc Increments the value stored in this slot by 1. Providing an
59           argument will cause the counter to be increased by specified
60           amount.
61
62       dec Decrements the value stored in this slot by 1. Providing an
63           argument will cause the counter to be increased by specified
64           amount.
65
66       reset
67           Resets the value stored in this slot to it's default value.
