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'.
