# ABSTRACT: Helper trait for Int attributes which represent counters
=pod
=head1 NAME
Moose::Meta::Attribute::Native::Trait::Counter - Helper trait for Int attributes which represent counters
=head1 VERSION
version 2.0401
=head1 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);
=head1 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.
=head1 DEFAULT TYPE
If you don't provide an C<isa> value for your attribute, it will default to
C<Num>.
=head1 PROVIDED METHODS
=over 4
=item * B<set($value)>
Sets the counter to the specified value and returns the new value.
This method requires a single argument.
=item * B<inc>
=item * B<inc($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.
=item * B<dec>
=item * B<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.
=item * B<reset>
Resets the value stored in this slot to its default value, and returns the new
value.
