Value::Object::DomainLabel - Value object representing 1 label of an Internet domain
This document describes Value::Object::DomainLabel version 0.12
use Value::Object::DomainLabel; my $com_label = Value::Object::DomainLabel->new( 'com' ); my $goog_label = Value::Object::DomainLabel->new( 'google' );
When working with Internet domains, it is sometimes useful to be able to validate one segment (or label) of the domain. The Value::Object::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.
Value::Object::DomainLabel
Trying to create a label that does not meet these criteria results in a thrown exception.
Create a value object if the supplied $label validates according to RFCs 1123 and 2181. Otherwise throw an exception.
$label
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.
new
Return a string matching the value of the Value object.
Value::Object::DomainLabel requires no configuration files or environment variables.
parent
