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.
