Valid values range from <i>0</i> to <b>BOOST_PP_LIMIT_REPEAT</b>. </dd> <dt>param</dt> <dd> The text of the parameter. <b>BOOST_PP_ENUM_SHIFTED_PARAMS</b> concatenates numbers ranging from <i>1</i> to <i>count</i> - <i>1</i> to generate parameters. </dd> </dl> <h4>Remarks</h4> <div> This macro expands to the comma-separated sequence: <div> <i>param</i> ## <i>1</i>, ... <i>param</i> ## <i>count</i> - <i>1</i> </div> </div> <div> This macro facilitates a typical usage of the library. Shifted parameter lists are common in template metaprograms. </div> <div> To use the <i>z</i> parameter passed from other macros that use <b>BOOST_PP_REPEAT</b>, see <b>BOOST_PP_ENUM_SHIFTED_PARAMS_Z</b>. </div> <div> Previously, this macro could not be used recursively inside <b>BOOST_PP_REPEAT</b>. This limitation no longer exists, as the library can automatically detect the next available repetition depth. </div> <h4>See Also</h4> <ul> <li><a href="limit_repeat.html">BOOST_PP_LIMIT_REPEAT</a></li> <li><a href="enum_shifted_params_z.html">BOOST_PP_SHIFTED_ENUM_PARAMS_<i>z</i></a></li> </ul> <h4>Requirements</h4> <div> <b>Header:</b> <a href="../headers/repetition/enum_shifted_params.html"><boost/preprocessor/repetition/enum_shifted_params.hpp></a> </div> <h4>Sample Code</h4> <div><pre> #include <<a href="../headers/repetition/enum_shifted_params.html">boost/preprocessor/repetition/enum_shifted_params.hpp</a>> <a href="enum_shifted_params.html">BOOST_PP_ENUM_SHIFTED_PARAMS</a>(3, class T) // expands to class T1, class T2 </pre></div> <hr size="1"> <div style="margin-left: 0px;"> <i>� Copyright <a href="http://www.housemarque.com" target="_top">Housemarque Oy</a> 2002</i> </br><i>� Copyright Paul Mensonides 2002</i> </div> <div style="margin-left: 0px;"> <p><small>Distributed under the Boost Software License, Version 1.0.
