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
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
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 RFC1035 zone file representation of the text
75 object.
76
77 unicode
78 $string = $text->unicode;
79
80 Conditionally quoted Unicode representation of the text object.
81
83 Coding strategy is intended to avoid creating unnecessary argument
84 lists and stack frames. This improves efficiency at the expense of code
85 readability.
86
87 Platform specific character coding features are conditionally compiled
88 into the code.
