SYNOPSIS

            

              
              
use MooseX::Validation::Doctypes;
doctype 'Location' => {
    id      => 'Str',
    city    => 'Str',
    state   => 'Str',
    country => 'Str',
    zipcode => 'Int',
};
doctype 'Person' => {
    id    => 'Str',
    name  => {
        # ... nested data structures
        first_name => 'Str',
        last_name  => 'Str',
    },
    title   => 'Str',
    # ... complex Moose types
    friends => 'ArrayRef[Person]',
    # ... using doctypes same as regular types
    address => 'Maybe[Location]',
};
use JSON;
# note the lack of Location,
# which is fine because it
# was Maybe[Location]
my $data = decode_json(q[
    {
        "id": "1234-A",
        "name": {
            "first_name" : "Bob",
            "last_name"  : "Smith",
         },
        "title": "CIO",
        "friends" : [],
    }
]);

DESCRIPTION

This module implements the actual type constraint that is created by the doctype function in MooseX::Validation::Doctypes. It is a subclass of Moose::Meta::TypeConstraint which adds a required doctype parameter, and automatically generates a constraint and message which validate based on that doctype (as described in the MooseX::Validation::Doctypes docs).

ATTRIBUTES

doctype

The doctype to validate. Required.
