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. AUTHOR
