NAME

       Class::Meta::Types::Perl - Perl data types

SYNOPSIS

         package MyApp::Thingy;
         use strict;
         use Class::Meta;
         use Class::Meta::Types::Perl;
         # OR...
         # use Class::Meta::Types::Perl 'affordance';
         # OR...
         # use Class::Meta::Types::Perl 'semi-affordance';

         BEGIN {
             # Create a Class::Meta object for this class.
             my $cm = Class::Meta->new( key => 'thingy' );

             # Add an integer attribute.
             $cm->add_attribute( name => 'my_hash',
                                 type => 'hash' );
             $cm->build;
         }

DESCRIPTION

       This module provides Perl data types for use with Class::Meta attributes.  Simply load it, then pass the
       name of one of its types to the "add_attribute()" method of a Class::Meta object. See Class::Meta::Type
       for more information on using and creating data types.

       The validation checks for Class::Meta::Types::Perl are provided by the Class::Meta::Type's support for
       object type validation, since Perl data types are understood by "UNIVERSAL::isa()".

       The data types created by Class::Meta::Types::Perl are:

       scalar
           A simple scalar value. This can be anything, and has no validation checks.

       scalarref
           A scalar reference. "UNIVERSAL::isa()" must return 'SCALAR'.

       array
       arrayref
           A array reference. "UNIVERSAL::isa()" must return 'ARRAY'.

       hash
       hashref
           A hash reference. "UNIVERSAL::isa()" must return 'HASH'.

       code
       coderef
       closure
           A code reference. Also known as a closure. "UNIVERSAL::isa()" must return 'CODE'.
