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:
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'.
This module is stored in an open repository at the following address:
