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
