NAME
Net::DNS::Text - DNS text representation
SYNOPSIS
use Net::DNS::Text;
$object = new Net::DNS::Text('example');
$string = $object->string;
$object = decode Net::DNS::Text( \$data, $offset );
( $object, $next ) = decode Net::DNS::Text( \$data, $offset );
$data = $object->encode;
$text = $object->value;
DESCRIPTION
The "Net::DNS::Text" module implements a class of text objects with
associated class and instance methods.
Each text object instance has a fixed identity throughout its lifetime.
METHODS
new
$object = new Net::DNS::Text('example');
Creates a text object which encapsulates a single character string
component of a resource record.
Arbitrary single-byte characters can be represented by \ followed by
exactly three decimal digits. Such characters are devoid of any special
meaning.
A character preceded by \ represents itself, without any special
interpretation.
decode
$object = decode Net::DNS::Text( \$buffer, $offset );
( $object, $next ) = decode Net::DNS::Text( \$buffer, $offset );
Creates a text object which represents the decoded data at the
indicated offset within the data buffer.
The argument list consists of a reference to a scalar containing the
wire-format data and offset of the text data.
The returned offset value indicates the start of the next item in the
data buffer.
encode
$data = $object->encode;
Returns the wire-format encoded representation of the text object
suitable for inclusion in a DNS packet buffer.
raw
$data = $object->raw;
Returns the wire-format encoded representation of the text object
without the explicit length field.
value
$value = $text->value;
Character string representation of the text object.
string
$string = $text->string;
Conditionally quoted zone file representation of the text object.
BUGS
Coding strategy is intended to avoid creating unnecessary argument
lists and stack frames. This improves efficiency at the expense of code
readability.
Platform specific character coding features are conditionally compiled
into the code.
