      curries  => {
          set       => { set_quantity => [ 'quantity' ] }
      }
  );
  # ...
  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'

Version

version 0.25

Overview

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

  # ...
  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

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.
