NAME

MooX::Value::DomainLabel - Value object representing 1 label of an Internet domain

VERSION

This document describes MooX::Value::DomainLabel version 0.01

SYNOPSIS

    use MooX::Value::DomainLabel;

    my $com_label  = MooX::Value::DomainLabel->new( 'com' );
    my $goog_label = MooX::Value::DomainLabel->new( 'google' );

DESCRIPTION

When working with Internet domains, it is sometimes useful to be able to validate one segment (or label) of the domain. The MooX::Value::DomainLabel provides that validation. The domain label specification is provided by the RFCs 1123 and 2181. A label must be between 1 and 63 ASCII characters in length. Only certain characters are allowed in the domain name label.

Trying to create a label that does not meet these criteria results in a thrown exception.

INTERFACE

MooX::Value::DomainLabel->new( $label )

Create a value object if the supplied $label validates according to RFCs 1123 and 2181. Otherwise throw an exception.

MooX::Value::DomainLabel->new_canonical( $label )

Create a value object if the supplied $label validates according to RFCs 1123 and 2181. Otherwise throw an exception.

Unlike the new method, the ASCII characters of the supplied $label are lowercased before the domain label is created. The canonical version of the domain label is always lowercase.

$dl->value()

Return a string matching the value of the Value object.
