VERSION
       version 0.25


SYNOPSIS
         package MyHomePage;
         use Moose;
         use MooseX::AttributeHelpers;

         has 'counter' => (
             metaclass => 'Counter',
             is        => 'ro',
             isa       => 'Num',
             default   => sub { 0 },
             provides  => {

                 dec => 'dec_counter',
                 reset => 'reset_counter',
             }
         );

         my $page = MyHomePage->new();

         $page->dec_counter; # same as $page->counter($page->counter - 1);


DESCRIPTION
       This module provides a simple counter attribute, which can be incremented and decremeneted.

       If your attribute definition does not include any of is, isa, default or provides but does use the
       "Counter" metaclass, then this module applies defaults as in the "SYNOPSIS" above. This allows for a very
       basic counter definition:

         has 'foo' => (metaclass => 'Counter');
         $obj->inc_foo;


METHODS
       meta
       method_provider
       has_method_provider
       helper_type
       process_options_for_provides
           Run before its superclass method.

       check_provides_values
           Run after its superclass method.


PROVIDED METHODS
       It is important to note that all those methods do in place modification of the value stored in the
       attribute.

       set Set the counter to the specified value.

       inc Increments the value stored in this slot by 1. Providing an argument will cause the counter to be
           increased by specified amount.

       dec Decrements the value stored in this slot by 1. Providing an argument will cause the counter to be
           increased by specified amount.

       reset
           Resets the value stored in this slot to it's default value.
