NAME

       MooseX::Blessed::Reconstruct - A Data::Visitor for creating Moose objects from blessed placeholders

SYNOPSIS

	       use MooseX::Blessed::Reconstruct;

	       my $obj = bless( {
		       init_arg_foo => "Blah",
		       arf => "yay",
	       }, "Foo" );

	       my $proper = MooseX::Blessed::Reconstruct->new->visit($obj);

	       # equivalent to:

	       my $proper = Foo->meta->new_object(%$obj);

	       # but recursive (and works with shared references)

DESCRIPTION

       The purpose of this module is to "fix up" blessed data into a real Moose object.

       This is used internally by MooseX::YAML but has no implementation details having to do with YAML itself.

METHODS

       See Data::Visitor

       visit_object $object
	   Calls "load_class" in Class::MOP on the "ref" of $object.

	   If there's a metaclass, calls "visit_object_with_meta", otherwise "visit_ref" is used to walk the object brutishly.

	   Returns a deep clone of the input structure with all the Moose objects reconstructed "properly".

       visit_object_with_meta $obj, $meta
	   Uses the metaclass $meta to create a new instance, registers the instance with Data::Visitor's cycle tracking, and then inflates it
	   using "new_object" in Moose::Meta::Class.

       prepare_args $obj
	   Collapses $obj into key value pairs to be used as init args to "new_object" in Moose::Meta::Class.

NAME

       Moose::Cookbook::Meta::Recipe1 - Welcome to the meta world (Why Go Meta?)

VERSION

       version 2.0205

SUMMARY

       You might want to read Moose::Manual::MOP if you haven't done so yet.

       If you've ever thought "Moose is great, but I wish it did X differently", then you've gone meta. The meta recipes demonstrate how to change
       and extend the way Moose works by extending and overriding how the meta classes (Moose::Meta::Class, Moose::Meta::Attribute, etc) work.

       The metaclass API is a set of classes that describe classes, roles, attributes, etc. The metaclass API lets you ask questions about a
       class, like "what attributes does it have?", or "what roles does the class do?"

       The metaclass system also lets you make changes to a class, for example by adding new methods or attributes.

       The interface presented by Moose.pm ("has", "with", "extends") is just a thin layer of syntactic sugar over the underlying metaclass
       system.

       By extending and changing how this metaclass system works, you can create your own Moose variant.

   Examples
       Let's say that you want to add additional properties to attributes. Specifically, we want to add a "label" property to each attribute, so
       we can write "My::Class->meta()->get_attribute('size')->label()". The first two recipes show two different ways to do this, one with a full
       meta-attribute subclass, and the other with an attribute trait.

       You might also want to add additional properties to your metaclass. For example, if you were writing an ORM based on Moose, you could
       associate a table name with each class via the class's metaclass object, letting you write "My::Class->meta()->table_name()".

SEE ALSO

       Many of the MooseX modules on CPAN implement metaclass extensions. A couple good examples include MooseX::Singleton and
       MooseX::AttributeHelpers. For a more complex example see Fey::ORM or Reaction.
