NAME

       Net::DNS::Text - DNS text representation

SYNOPSIS

           use Net::DNS::Text;

           $object = Net::DNS::Text->new('example');
           $string = $object->string;

           $object = Net::DNS::Text->decode( \$data, $offset );
           ( $object, $next ) = Net::DNS::Text->decode( \$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 = Net::DNS::Text->new('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 = Net::DNS::Text->decode( \$buffer, $offset );

           ( $object, $next ) = Net::DNS::Text->decode( \$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 RFC1035 zone file representation of the text object.

   unicode
           $string = $text->unicode;

       Conditionally quoted Unicode 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.
