| 82 | =head1 DESCRIPTION | ||||
| 83 | |||||
| 84 | This module provides a simple counter attribute, which can be | ||||
| 85 | incremented and decremeneted. | ||||
| 86 | |||||
| 87 | If your attribute definition does not include any of I<is>, I<isa>, | ||||
| 88 | I<default> or I<provides> but does use the C<Counter> metaclass, | ||||
| 89 | then this module applies defaults as in the L</SYNOPSIS> | ||||
| 90 | above. This allows for a very basic counter definition: | ||||
| 91 | |||||
| 92 | has 'foo' => (metaclass => 'Counter'); | ||||
| 93 | $obj->inc_foo; | ||||
| 94 | |||||
| 95 | =head1 METHODS | ||||
| 96 | |||||
| 97 | =over 4 | ||||
| 98 | |||||
| 99 | =item B<meta> | ||||
| 100 | |||||
| 101 | =item B<method_provider> | ||||
| 102 | |||||
| 103 | =item B<has_method_provider> | ||||
| 104 | |||||
| 105 | =item B<helper_type> | ||||
| 106 | |||||
| 107 | =item B<process_options_for_provides> | ||||
| 108 | |||||
| 109 | Run before its superclass method. | ||||
| 110 | |||||
| 111 | =item B<check_provides_values> | ||||
| 112 | |||||
| 113 | Run after its superclass method. | ||||

| 117 | =head1 PROVIDED METHODS | ||||
| 118 | |||||
| 119 | It is important to note that all those methods do in place | ||||
| 120 | modification of the value stored in the attribute. | ||||
| 121 | |||||
| 122 | =over 4 | ||||
| 123 | |||||
| 124 | =item I<set> | ||||
| 125 | |||||
| 126 | Set the counter to the specified value. | ||||
| 127 | |||||
| 128 | =item I<inc> | ||||
| 129 | |||||
| 130 | Increments the value stored in this slot by 1. Providing an argument will | ||||
| 131 | cause the counter to be increased by specified amount. | ||||
| 132 | |||||
| 133 | =item I<dec> | ||||
| 134 | |||||
| 135 | Decrements the value stored in this slot by 1. Providing an argument will | ||||
| 136 | cause the counter to be increased by specified amount. | ||||
| 137 | |||||
| 138 | =item I<reset> | ||||
| 139 | |||||
| 140 | Resets the value stored in this slot to it's default value. | ||||

| 147 | exception. If you find a bug please either email me, or add the bug | ||||
