Class::Meta::Types::Perl - Perl data types
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; }
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.
add_attribute()
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().
UNIVERSAL::isa()
The data types created by Class::Meta::Types::Perl are:
A simple scalar value. This can be anything, and has no validation checks.
A scalar reference. UNIVERSAL::isa() must return 'SCALAR'.
A array reference. UNIVERSAL::isa() must return 'ARRAY'.
A hash reference. UNIVERSAL::isa() must return 'HASH'.
A code reference. Also known as a closure. UNIVERSAL::isa() must return 'CODE'.
