MooseX::Blessed::Reconstruct

NAME

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

VERSION

version 1.00

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.
