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


version 1.00


        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)


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.


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.
