NAME
MooseX::NonMoose::Meta::Role::Constructor - constructor method trait for MooseX::NonMoose VERSION
version 0.22 SYNOPSIS
package My::Moose; use Moose (); use Moose::Exporter; Moose::Exporter->setup_import_methods; sub init_meta { shift; my %options = @_; Moose->init_meta(%options); Moose::Util::MetaRole::apply_metaclass_roles( for_class => $options{for_class}, metaclass_roles => ['MooseX::NonMoose::Meta::Role::Class'], constructor_class_roles => ['MooseX::NonMoose::Meta::Role::Constructor'], ); return Class::MOP::class_of($options{for_class}); } DESCRIPTION
This trait implements inlining of the constructor for classes using the MooseX::NonMoose::Meta::Role::Class metaclass trait; it has no effect unless that trait is also used. See those docs and the docs for MooseX::NonMoose for more information. AUTHOR

NAME
MooseX::NonMoose - easy subclassing of non-Moose classes VERSION
version 0.22 SYNOPSIS
package Term::VT102::NBased; use Moose; use MooseX::NonMoose; extends 'Term::VT102'; has [qw/x_base y_base/] => ( is => 'ro', isa => 'Int', default => 1, ); around x => sub { my $orig = shift; my $self = shift; $self->$orig(@_) + $self->x_base - 1; }; # ... (wrap other methods) no Moose; # no need to fiddle with inline_constructor here __PACKAGE__->meta->make_immutable; my $vt = Term::VT102::NBased->new(x_base => 0, y_base => 0); DESCRIPTION
"MooseX::NonMoose" allows for easily subclassing non-Moose classes with Moose, taking care of the annoying details connected with doing this, such as setting up proper inheritance from Moose::Object and installing (and inlining, at "make_immutable" time) a constructor that makes sure things like "BUILD" methods are called. It tries to be as non-intrusive as possible - when this module is used, inheriting from non-Moose classes and inheriting from Moose classes should work identically, aside from the few caveats mentioned below. One of the goals of this module is that including it in a Moose::Exporter-based package used across an entire application should be possible, without interfering with classes that only inherit from Moose modules, or even classes that don't inherit from anything at all. There are several ways to use this module. The most straightforward is to just "use MooseX::NonMoose;" in your class; this should set up everything necessary for extending non-Moose modules. MooseX::NonMoose::Meta::Role::Class and MooseX::NonMoose::Meta::Role::Constructor can also be applied to your metaclasses manually, either by passing a "-traits" option to your "use Moose;" line, or by applying them using Moose::Util::MetaRole in a Moose::Exporter-based package. MooseX::NonMoose::Meta::Role::Class is the part that provides the main functionality of this module; if you don't care about inlining, this is all you need to worry about. Applying MooseX::NonMoose::Meta::Role::Constructor as well will provide an inlined constructor when you immutabilize your class. "MooseX::NonMoose" allows you to manipulate the argument list that gets passed to the superclass constructor by defining a "FOREIGNBUILDARGS" method. This is called with the same argument list as the "BUILDARGS" method, but should return a list of arguments to pass to the superclass constructor. This allows "MooseX::NonMoose" to support superclasses whose constructors would get confused by the extra arguments that Moose requires (for attributes, etc.) Not all non-Moose classes use "new" as the name of their constructor. This module allows you to extend these classes by explicitly stating which method is the constructor, during the call to "extends". The syntax looks like this: extends 'Foo' => { -constructor_name => 'create' }; similar to how you can already pass "-version" in the "extends" call in a similar way. BUGS
/CAVEATS o The reference that the non-Moose class uses as its instance type must match the instance type that Moose is using. Moose's default instance type is a hashref, but other modules exist to make Moose use other instance types. MooseX::InsideOut is the most general solution - it should work with any class. For globref-based classes in particular, MooseX::GlobRef will also allow Moose to work. For more information, see the "032-moosex-insideout" and "033-moosex-globref" tests bundled with this dist. o Completely overriding the constructor in a class using "MooseX::NonMoose" (i.e. using "sub new { ... }") currently doesn't work, although using method modifiers on the constructor should work identically to normal Moose classes.

o "How do I make non-Moose constructors work with Moose?" in Moose::Manual::FAQ o MooseX::Alien serves the same purpose, but with a radically different (and far more hackish) implementation. SUPPORT
