|
|
The <b>BOOST_PP_ENUM_BINARY_PARAMS_Z</b> macro generates a comma-separated list of binary parameters.
|
|
It reenters <b>BOOST_PP_REPEAT</b> with maximum efficiency.
|
|
</div>
|
|
<h4>Usage</h4>
|
|
<div class="code">
|
|
<b>BOOST_PP_ENUM_BINARY_PARAMS_Z</b>(<i>z</i>, <i>count</i>, <i>p1</i>, <i>p2</i>)
|
|
</div>
|
|
<h4>Arguments</h4>
|
|
<dl>
|
|
<dt>z</dt>
|
|
<dd>
|
|
The next available <b>BOOST_PP_REPEAT</b> dimension.
|
|
</dd>
|
|
<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>p1</dt>
|
|
<dd>
|
|
The text of the first part of the parameter.
|
|
<b>BOOST_PP_ENUM_BINARY_PARAMS</b> concatenates numbers ranging from <i>0</i> to <i>count</i> - <i>1</i>
|
|
to generate parameters.
|
|
</dd>
|
|
<dt>p2</dt>
|
|
<dd>
|
|
The text of the first part of the parameter.
|
|
<b>BOOST_PP_ENUM_BINARY_PARAMS</b> concatenates numbers ranging from <i>0</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>p1</i> ## <i>0</i> <i>p2</i> ## <i>0</i>, <i>p1</i> ## <i>1</i> <i>p2</i> ## <i>1</i>, ... <i>p1</i> ## <i>count</i> - <i>1</i> <i>p2</i> ## <i>count</i> - <i>1</i>
|
|
</div>
|
|
</div>
|
|
<div>
|
|
This macro is a replacement for both <b>BOOST_PP_ENUM_PARAMS_WITH_A_DEFAULT</b> and <b>BOOST_PP_ENUM_PARAMS_WITH_DEFAULTS</b>.
|
|
</div>
|
