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 CWadd_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 CWUNIVERSAL::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. CWUNIVERSAL::isa() must return 'SCALAR'.
array
arrayref
A array reference. CWUNIVERSAL::isa() must return 'ARRAY'.
hash
hashref
A hash reference. CWUNIVERSAL::isa() must return 'HASH'.
code
coderef
closure
A code reference. Also known as a closure. CWUNIVERSAL::isa() must return 'CODE'.
