        package MyApp::Schema::PersonName;

        use MongoDBx::Class::Moose; # use this instead of Moose
        use namespace::autoclean;
        
        with 'MongoDBx::Class::EmbeddedDocument';

        has 'first_name' => (is => 'ro', isa => 'Str', required => 1, writer => 'set_first_name');
        
        has 'middle_name' => (is => 'ro', isa => 'Str', predicate => 'has_middle_name', writer => 'set_middle_name');

        has 'last_name' => (is => 'ro', isa => 'Str', required => 1, writer => 'set_last_name');

        sub name {
                my $self = shift;

                my $name = $self->first_name;
                $name .= ' '.$self->middle_name.' ' if $self->has_middle_name;
                $name .= $self->last_name;

DESCRIPTION

MongoDBx::Class::EmbeddedDocument is a Moose role meant to be consumed by document classes representing embedded documents. These are documents that are entirely contained within parent MongoDB documents.

The role provides expanded embedded documents with some common attributes and useful methods.

ATTRIBUTES

_collection

The MongoDBx::Class::Collection object representing the MongoDB collection in which this embedded document is stored (more correctly, the collection in which the MongoDBx::Class::Document holding this embedded document is stored). This is a required attribute.

_class

A string. The name of the document class of this embedded document. A required attribute.

METHODS

The following methods are provided:

as_hashref()

Returns the embedded document as a hash reference, without the _collection and _class attributes (if they exist).

INTERNAL METHODS

_database()

Convenience shortcut for running $embd_doc->_collection->_database.

_attributes()

Returns a list of names of all attributes the embedded document object has, minus '_collection' and '_class', sorted alphabetically.
