NAME

       Sub::HandlesVia::Manual::WithMoose - using Sub::HandlesVia with Moose

SYNOPSIS

        package Kitchen {
          use Moose;
          use Sub::HandlesVia;
          use Types::Standard qw( ArrayRef Str );

          has food => (
            is          => 'ro',
            isa         => ArrayRef[Str],
            handles_via => 'Array',
            default     => sub { [] },
            handles     => {
              'add_food'    => 'push',
              'find_food'   => 'grep',
            },
          );
        }

       (If you have a moose in your kitchen, that might be a disaster!)

MANUAL

       Sub::HandlesVia allows you to delegate methods from your class to the values of your
       objects' attributes.

       Conceptually, it allows you to define "$object->push_number($n)" to be a shortcut for
       "$object->numbers->push($n)" except that "$object->numbers" is an arrayref, so doesn't
       have methods you can call on it like "push".

       Moose does have a built-in feature (native traits) which provides a more limited version
       of this.

   Which Methods Can Be Delegated To?
       The "handles_via" option indicates which library of methods should be available. Valid
       values include Array, Blessed, Bool, Code, Counter, Enum, Hash, Number, Scalar, and
       String.

       An arrayref can be provided for "handles_via", though many of the options are conceptually
       contradictory.

        handles_via => [ 'Number', 'Scalar' ]

   Moose Native Types
       Although the synopsis shows Types::Standard being used for type constraints, Moose native
       types should also work fine.

        package Kitchen {
          use Moose;
          use Sub::HandlesVia;

          has food => (
            is          => 'ro',
            isa         => 'ArrayRef[Str]',
            handles_via => 'Array',
            default     => sub { [] },
            handles     => {
              'add_food'    => 'push',
              'find_food'   => 'grep',
            },
          );
        }

   True Moose Native Traits Drop-In Syntax
       Sub::HandlesVia will also recognize native-traits-style traits. It will jump in and handle
       them before Moose notices!

        package Kitchen {
          use Moose;
          use Sub::HandlesVia;

          has food => (
            is          => 'ro',
            isa         => 'ArrayRef[Str]',
            traits      => ['Array'],
            default     => sub { [] },
            handles     => {
              'add_food'    => 'push',
              'find_food'   => 'grep',
            },
          );
        }
