| 8 | <div style="margin-left: 0px;"> The <b>BOOST_PP_TUPLE_REPLACE</b> macro |
| 9 | replaces an element in a <i>tuple</i>.</div> |
| 10 | <h4>Usage</h4> |
| 11 | <div class="code"> <b>BOOST_PP_TUPLE_REPLACE</b>(<i>tuple</i>, <i>i</i>, <i>elem</i>) |
| 12 | <a href="../topics/variadic_macros.html#VNotation"><sup>(v)</sup></a></div> |
| 13 | <h4>Arguments</h4> |
| 14 | <dl> |
| 15 | <dt>tuple</dt> |
| 16 | <dd> A <i>tuple</i> to replace an element in. </dd> |
| 17 | <dt>i</dt> |
| 18 | <dd> The zero-based position in <i>tuple</i> of the element to be |
| 19 | replaced. Valid values range from <i>0</i> to <b>BOOST_PP_TUPLE_SIZE</b>(<i>tuple</i>) |
| 20 | - <i>1</i>.</dd> |
| 21 | <dt>elem</dt> |
| 22 | <dd> The replacement element. </dd> |
| 23 | </dl> |
| 24 | <h4>Remarks</h4> |
| 25 | <div> This macro uses <b>BOOST_PP_WHILE</b> interally. Therefore, to |
| 26 | use the <i>d</i> parameter passed from other macros that use <b>BOOST_PP_WHILE</b>, |
| 27 | see <b>BOOST_PP_TUPLE_REPLACE_D</b>.</div> |
