Class::Meta::Types::Numeric − Numeric data types
package MyApp::Thingy; use strict; use Class::Meta; use Class::Meta::Types::Numeric; # OR... # use Class::Meta::Types::Numeric 'affordance'; # OR... # use Class::Meta::Types::Numeric '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 => 'age', type => 'integer' ); $cm−>build; }
This module provides numeric 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 to create attributes of the numeric data type. See Class::Meta::Type for more information on using and creating data types.
The validation checks for Class::Meta::Types::Numeric are provided by the Data::Types module. Consult its documentation to find out what it considers to be a number and what’s not.
