NAME

6       Net::DNS::Text - DNS text representation
7

SYNOPSIS

9           use Net::DNS::Text;
10
11           $object = Net::DNS::Text->new('example');
12           $string = $object->string;
13
14           $object = Net::DNS::Text->decode( \$data, $offset );
15           ( $object, $next ) = Net::DNS::Text->decode( \$data, $offset );
16
17           $data = $object->encode;
18           $text = $object->value;
19

DESCRIPTION

21       The "Net::DNS::Text" module implements a class of text objects with
22       associated class and instance methods.
23
24       Each text object instance has a fixed identity throughout its lifetime.
25

METHODS

27   new
28           $object = Net::DNS::Text->new('example');
29
30       Creates a text object which encapsulates a single character string
31       component of a resource record.
32
33       Arbitrary single-byte characters can be represented by \ followed by
34       exactly three decimal digits. Such characters are devoid of any special
35       meaning.
36
37       A character preceded by \ represents itself, without any special
38       interpretation.
39
40   decode
41           $object = Net::DNS::Text->decode( \$buffer, $offset );
42
43           ( $object, $next ) = Net::DNS::Text->decode( \$buffer, $offset );
44
45       Creates a text object which represents the decoded data at the
46       indicated offset within the data buffer.
47
48       The argument list consists of a reference to a scalar containing the
49       wire-format data and offset of the text data.
50
51       The returned offset value indicates the start of the next item in the
52       data buffer.
53
54   encode
55           $data = $object->encode;
56
57       Returns the wire-format encoded representation of the text object
58       suitable for inclusion in a DNS packet buffer.
59
60   raw
61           $data = $object->raw;
62
63       Returns the wire-format encoded representation of the text object
64       without the explicit length field.
65
66   value
67           $value = $text->value;
68
69       Character string representation of the text object.
70
71   string
72           $string = $text->string;
73
74       Conditionally quoted zone file representation of the text object.
75

BUGS

77       Coding strategy is intended to avoid creating unnecessary argument
78       lists and stack frames. This improves efficiency at the expense of code
79       readability.
80
81       Platform specific character coding features are conditionally compiled
82       into the code.
