60 This module provides a simple counter attribute, which can be incremented and
61 decremented. It is important to note that all those methods do in place
62 modification of the value stored in the attribute.
64 If your attribute definition does not include any of I<is>, I<isa>,
65 I<default> or I<provides> but does use the C<Counter> metaclass,
66 then this module applies defaults as in the L</SYNOPSIS>
67 above. This allows for a very basic counter definition:
69 has 'foo' => (metaclass => 'Counter');
72 =head1 PROVIDED METHODS
74 The methods for this metaclass are provided by
75 L<MooseX::AttributeHelpers::MethodProvider::Counter>.
79 All complex software has bugs lurking in it, and this module is no
