NAME

Data::Type - robust and extensible data- and valuetype system

VERSION

0.02.01 (Thu Dec 31 13:59:04 2009)

DESCRIPTION

This module delivers an easy, generic and unified interface to type related CPAN modules. They all have one common purpose: reporting if data has some "characteristics". And this module wraps that with a clean api.

SYNOPSIS

use Data::Type qw(:is +ALL);

is STD::EMAIL or warn;

warn if isnt STD::CREDITCARD( 'MASTERCARD', 'VISA' );

try
{
  valid( '9999-12-31 23:59:59', DB::DATETIME );
}
catch Data::Type::Exception with
{
  print $e->to_string foreach @_;
};

EXAMPLES

Visit the Data::Type::Docs::Howto to explore how to use this module for DBI, CGI, Getopt and more scenarios.

INSTALLATION

I highly recommend to use CPAN for one-stop-shop installation:

perl -MCPAN -e "install Data::Type"

SUPPORTED TYPES

All types are grouped and though belong to a collection. The collection is identified by a short id. All members are living in a namespace that is prefixed with it (uppercased).

Standard Collection ('STD')

This is a heterogenous collection of datatypes which is loaded by default. It contains various issues from CPAN modules (i.e. business, creditcard, email, markup, regexps and etc.) and some everyday things. See Data::Type::Collection::Std.

W3C/XML-Schema Collection ('W3C')

A nearly 1-to-1 use of XML::Schema datatypes. It is nearly complete and works off the shelf. Please visit the XMLSchema http://www.w3.org/TR/xmlschema-2/ homepage for sophisticated documentation. See Data::Type::Collection::W3C.

Database Collection ('DB')

Common database table types (VARCHAR, TINYTEXT, TIMESTAMP, etc.). See Data::Type::Collection::DB.

Biological Collection ('BIO')

Everything that is related to biological matters (DNA, RNA, etc.). See Data::Type::Collection::Bio.

Chemistry Collection ('CHEM')

Everything that is related to chemical matters (Atoms, etc.). See Data::Type::Collection::Chem.

Perl5 Collection ('PERL')

Reserved and undecided. See Data::Type::Collection::Perl.

Perl6 Apocalypse Collection ('PERL6')

Placeholder for the Apocalypse and Synopsis 6 suggested datatypes for perl6. See Data::Type::Collection::Perl6.

[Note] ALL is a an alias for all available collections at once.

PREREQUISITES

Following modules get automatically installed via the CPAN module. See INSTALLATION above. Data::Type has a mechanism for delayed loading of modules. This means modules are loaded only when the used types require them, not all at once.

READON
