MooseX::AttributeHelpers::Trait::Counter(3pm)		User Contributed Perl Documentation	     MooseX::AttributeHelpers::Trait::Counter(3pm)

NAME

       MooseX::AttributeHelpers::Counter - simple counter attribute

SYNOPSIS

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

	 has 'counter' => (
	     metaclass => 'Counter',
	     is        => 'ro',
	     isa       => 'Num',
	     default   => sub { 0 },
	     provides  => {
		 inc => 'inc_counter',
		 dec => 'dec_counter',
		 reset => 'reset_counter',
	     }
	 );

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

BUGS

       All complex software has bugs lurking in it, and this module is no exception. If you find a bug please either email me, or add the bug to
       cpan-RT.
