MooseX::AttributeHelpers - Extend your attribute interfaces

=head1 SYNOPSIS

  package MyClass;
  use Moose;
  use MooseX::AttributeHelpers;

  has 'mapping' => (
      metaclass => 'Collection::Hash',
      is        => 'rw',
      isa       => 'HashRef[Str]',
      default   => sub { {} },
      provides  => {
          exists    => 'exists_in_mapping',
          keys      => 'ids_in_mapping',
          get       => 'get_mapping',
          set       => 'set_mapping',
      },
  );

  # ...

  my $obj = MyClass->new;
  $obj->set_mapping(4, 'foo');
  $obj->set_mapping(5, 'bar');
  $obj->set_mapping(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;

=head1 DESCRIPTION

While L<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 L</SYNOPSIS>, you specify the extension via the 
C<metaclass> parameter. Available meta classes are:

=over

=item L<Number|MooseX::AttributeHelpers::Number>

Common numerical operations.

=item L<Counter|MooseX::AttributeHelpers::Counter>

Methods for incrementing and decrementing a counter attribute.

=item L<Counter|MooseX::AttributeHelpers::Bool>

Common methods for boolean values.

=item L<Collection::Hash|MooseX::AttributeHelpers::Collection::Hash>

Common methods for hash references.

=item L<Collection::Array|MooseX::AttributeHelpers::Collection::Array>

Common methods for array references.

=item L<Collection::List|MooseX::AttributeHelpers::Collection::List>

Common list methods for array references.

=head1 CAVEAT

This is an early release of this module. Right now it is in great need 
of documentation and tests in the test suite. However, we have used this 
module to great success at C<$work> where it has been tested very thoroughly
and deployed into a major production site.

I plan on getting better docs and tests in the next few releases, but until 
then please refer to the few tests we do have and feel free email and/or 
message me on irc.perl.org if you have any questions.

=head1 TODO

We need tests and docs badly.

=head1 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.
