MooseX::Blessed::Reconstruct(3) 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.
