         );

         # ...

         my $obj = MyClass->new;
         $obj->set_quantity(10);      # quantity => 10
         $obj->set_mapping(4, 'foo'); # 4 => 'foo'
         $obj->set_mapping(5, 'bar'); # 5 => 'bar'
         $obj->set_mapping(6, 'baz'); # 6 => 'baz'

         # prints 'bar'
         print $obj->get_mapping(5) if $obj->exists_in_mapping(5);

         # prints '4, 5, 6'
         print join ', ', $obj->ids_in_mapping;

DESCRIPTION

       This distribution is deprecated. The features it provides have been added to the Moose
       core code as Moose::Meta::Attribute::Native. This distribution should not be used by any
       new code.

       While Moose attributes provide you with a way to name your accessors, readers, writers,
       clearers and predicates, this library provides commonly used attribute helper methods for
       more specific types of data.

       As seen in the "SYNOPSIS", you specify the extension via the "metaclass" parameter.
       Available meta classes are:

PARAMETERS

   provides
       This points to a hashref that uses "provider" for the keys and "method" for the values.
       The method will be added to the object itself and do what you want.

   curries
       This points to a hashref that uses "provider" for the keys and has two choices for the
       value:

       You can supply "{method => [ @args ]}" for the values.  The method will be added to the
       object itself (always using @args as the beginning arguments).

       Another approach to curry a method provider is to supply a coderef instead of an arrayref.
       The code ref takes $self, $body, and any additional arguments passed to the final method.

         # ...

         curries => {
             grep => {
                 times_with_day => sub {
                     my ($self, $body, $datetime) = @_;
                     $body->($self, sub { $_->ymd eq $datetime->ymd });
                 }
             }
         }

         # ...

         $obj->times_with_day(DateTime->now); # takes datetime argument, checks day

METHOD PROVIDERS

       Number
           Common numerical operations.

       String
           Common methods for string operations.

       Counter
           Methods for incrementing and decrementing a counter attribute.

       Bool
           Common methods for boolean values.

       Collection::Hash
           Common methods for hash references.

       Collection::ImmutableHash
           Common methods for inspecting hash references.

       Collection::Array
           Common methods for array references.

       Collection::List
           Common list methods for array references.

DEPRECATION NOTICE

       The functionality in this family of modules is now implemented in the Moose core as
       Moose::Meta::Attribute::Native.  No more development is being done on
       MooseX::AttributeHelpers, so we encourage you to switch to native attribute traits.
