Such characters are devoid of any special meaning. .PP A character preceded by \e represents itself, without any special interpretation. .SS "decode" .IX Subsection "decode" .Vb 1 \& $object = Net::DNS::Text\->decode( \e$buffer, $offset ); \& \& ( $object, $next ) = Net::DNS::Text\->decode( \e$buffer, $offset ); .Ve .PP Creates a text object which represents the decoded data at the indicated offset within the data buffer. .PP The argument list consists of a reference to a scalar containing the wire-format data and offset of the text data. .PP The returned offset value indicates the start of the next item in the data buffer. .SS "encode" .IX Subsection "encode" .Vb 1 \& $data = $object\->encode; .Ve .PP Returns the wire-format encoded representation of the text object suitable for inclusion in a \s-1DNS\s0 packet buffer. .SS "raw" .IX Subsection "raw" .Vb 1 \& $data = $object\->raw; .Ve .PP Returns the wire-format encoded representation of the text object without the explicit length field. .SS "value" .IX Subsection "value" .Vb 1 \& $value = $text\->value; .Ve .PP Character string representation of the text object. .SS "string" .IX Subsection "string" .Vb 1 \& $string = $text\->string; .Ve .PP Conditionally quoted \s-1RFC1035\s0 zone file representation of the text object. .SS "unicode" .IX Subsection "unicode" .Vb 1 \& $string = $text\->unicode; .Ve .PP Conditionally quoted Unicode representation of the text object. .SH "BUGS" .IX Header "BUGS" Coding strategy is intended to avoid creating unnecessary argument lists and stack frames. This improves efficiency at the expense of code readability. .PP Platform specific character coding features are conditionally compiled into the code. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright (c)2009\-2011 Dick Franks. .PP All rights reserved. .SH "LICENSE" .IX Header "LICENSE" Permission to use, copy, modify, and distribute this software and its documentation for any purpose and without fee is hereby granted, provided that the original copyright notices appear in all copies and that both copyright notice and this permission notice appear in supporting documentation, and that the name of the author not be used in advertising or publicity pertaining to distribution of the software without specific prior written permission. .PP \&\s-1THE SOFTWARE IS PROVIDED \*(L"AS IS\*(R", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
