- <div style="margin-left: 0px;">
- The <b>BOOST_PP_ENUM_PARAMS_WITH_A_DEFAULT</b> macro generates a comma-separated list of parameters with a default argument.
- </div>
- <h4>Usage</h4>
- <div class="code">
- <b>BOOST_PP_ENUM_PARAMS_WITH_A_DEFAULT</b>(<i>count</i>, <i>param</i>, <i>def</i>)
- </div>
- <h4>Arguments</h4>
- <dl>
- <dt>count</dt>
- <dd>
- The number of parameters to generate.
- 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_PARAMS_WITH_A_DEFAULT</b> concatenates numbers ranging from <i>0</i> to <i>count</i> - <i>1</i>
- to generate parameters.
- </dd>
- <dt>def</dt>
- <dd>
- The default value that trails each parameter.
- </dd>
- </dl>
- <h4>Remarks</h4>
- <div>
- This macro expands to the comma-separated sequence:
- <div>
- <i>param</i> ## <i>0</i> = <i>def</i>, <i>param</i> ## <i>1</i> = <i>def</i>, ... <i>param</i> ## <i>count</i> - <i>1</i> = <i>def</i>
- </div>
- </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>
- <div>
- This macro is deprecated.
- It only exists for backward compatibility.
- Use <b>BOOST_PP_ENUM_BINARY_PARAMS</b> with <b>BOOST_PP_INTERCEPT</b> instead:
- <div>
- <b>BOOST_PP_ENUM_BINARY_PARAMS</b>(<i>count</i>, <i>param</i>, = <i>def</i> <b>BOOST_PP_INTERCEPT</b>)
- </div>
- </div>
