NAME

MooseX::SlurpyConstructor - Make your object constructor collect all unknown attributes

VERSION

version 1.30

SYNOPSIS

    package My::Class;

    use Moose;
    use MooseX::SlurpyConstructor;

    has fixed => (
        is      => 'ro',
    );

    has slurpy => (
        is      => 'ro',
        slurpy  => 1,
    );

    package main;

    ASDF->new({
        fixed => 100, unknown1 => "a", unknown2 => [ 1..3 ]
    })->dump;

    # returns:
    #   $VAR1 = bless( {
    #       'slurpy' => {
    #           'unknown2' => [
    #               1,
    #               2,
    #               3
    #           ],
    #           'unknown1' => 'a'
    #       },
    #       'fixed' => 100
    #   }, 'ASDF' );

DESCRIPTION

Including this module within Moose-based classes, and declaring an attribute as 'slurpy' will allow capturing of all unknown constructor arguments in the given attribute.

As of Moose 1.9900, this module can also be used in a role, in which case the constructor of the consuming class will become slurpy.

OPTIONAL RESTRICTIONS

No additional options are added to your slurpy attribute, so if you want to make it read-only, or restrict its type constraint to a HashRef of specific types, you should state that yourself. Typical usage may include any or all of the options below:

    has slurpy => (
        is => 'ro',
        isa => 'HashRef',
        init_arg => undef,
        lazy => 1,
        default => sub { {} },
        traits => ['Hash'],
        handles => {
            slurpy_values => 'elements',
        },
    );

For more information on these options, see Moose::Manual::Attributes and Moose::Meta::Attribute::Native::Trait::Hash.

HISTORY

This module was originally written by Mark Morgan <makk384@gmail.com>, with some bugfix patches by Christian Walde.

It was rewritten for Moose 2.0 by Karen Etheridge <ether@cpan.org>, drawing heavily on MooseX::StrictConstructor.

ACKNOWLEDGEMENTS

Thanks to the folks from the Moose mailing list and IRC channels for helping me find my way around some of the Moose bits I didn't know of before writing this module.
