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

VERSION
       version 2.2005

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
       o   set($value)

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

	   This	method requires	a single argument.

       o   inc

       o   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.

       o   dec

       o   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.

       o   reset

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