NAME
       Moose::Meta::Attribute::Native::Trait::Counter - Helper trait for Int attributes which
       represent counters

VERSION
       version 2.1213

SYNOPSIS
         package MyHomePage;
         use Moose;

         has 'counter' => (
             traits  => ['Counter'],
             is      => 'ro',
             isa     => 'Num',
             default => 0,
             handles => {
                 inc_counter   => 'inc',
                 dec_counter   => 'dec',
                 reset_counter => 'reset',
             },
         );

         my $page = MyHomePage->new();
         $page->inc_counter;    # same as $page->counter( $page->counter + 1 );
         $page->dec_counter;    # same as $page->counter( $page->counter - 1 );

         my $count_by_twos = 2;
         $page->inc_counter($count_by_twos);

DESCRIPTION
       This trait provides native delegation methods for counters. A counter can be any sort of
       number (integer or not). The delegation methods allow you to increment, decrement, or
       reset the value.

DEFAULT TYPE
       If you don't provide an "isa" value for your attribute, it will default to "Num".

PROVIDED METHODS
       ·   set($value)

           Sets the counter to the specified value and returns the new value.

           This method requires a single argument.

       ·   inc

       ·   inc($arg)

           Increases the attribute value by the amount of the argument, or by 1 if no argument is
           given. This method returns the new value.

           This method accepts a single argument.

       ·   dec

       ·   dec($arg)

           Decreases the attribute value by the amount of the argument, or by 1 if no argument is
           given. This method returns the new value.

           This method accepts a single argument.

       ·   reset

           Resets the value stored in this slot to its default value, and returns the new value.
