NAME
MooseX::Blessed::Reconstruct - A Data::Visitor for creating Moose objects from blessed placeholdersSYNOPSIS
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); $proper->BUILDALL({%$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.
After the object is built, "BUILDALL" is called if the object implements it.
- prepare_args $obj
- Collapses $obj into key value pairs to be used as init args to ``new_object'' in Moose::Meta::Class.
