These are versions which have an underscore 33 D suffix, take the next available BOOST_PP_WHILE iteration as their first parameter, 34 and then have the exact same functionality as their unsuffixed equivalents. 35 They can be used in BOOST_PP_WHILE loops to provide slightly quicker preprocessing 36 but, as the documentation for BOOST_PP_WHILE and BOOST_PP_WHILE_##d explain, 37 they do not have to be used. 38 </p> 39<p> 40 These macros are: 41 </p> 42<p> 43 Arrays 44 </p> 45<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "> 46<li class="listitem"> 47 BOOST_VMD_IS_ARRAY_D 48 </li> 49<li class="listitem"> 50 BOOST_VMD_IS_EMPTY_ARRAY_D 51 </li> 52<li class="listitem"> 53 BOOST_VMD_ASSERT_IS_ARRAY_D 54 </li> 55</ul></div> 56<p> 57 Identifiers 58 </p> 59<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "> 60<li class="listitem"> 61 BOOST_VMD_IS_IDENTIFIER_D 62 </li> 63<li class="listitem"> 64 BOOST_VMD_ASSERT_IS_IDENTIFIER_D 65 </li> 66</ul></div> 67<p> 68 Lists 69 </p> 70<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "> 71<li class="listitem"> 72 BOOST_VMD_IS_LIST_D 73 </li> 74<li class="listitem"> 75 BOOST_VMD_IS_EMPTY_LIST_D 76 </li> 77<li class="listitem"> 78 BOOST_VMD_ASSERT_IS_LIST_D 79 </li> 80</ul></div> 81<p> 82 Sequences 83 </p> 84<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "> 85<li class="listitem"> 86 BOOST_VMD_ELEM_D 87 </li> 88<li class="listitem"> 89 BOOST_VMD_ENUM_D 90 </li> 91<li class="listitem"> 92 BOOST_VMD_EQUAL_D 93 </li> 94<li class="listitem"> 95 BOOST_VMD_GET_TYPE_D 96 </li> 97<li class="listitem"> 98 BOOST_VMD_IS_MULTI_D 99 </li> 100<li class="listitem"> 101 BOOST_VMD_IS_UNARY_D 102 </li> 103<li class="listitem"> 104 BOOST_VMD_NOT_EQUAL_D 105 </li> 106<li class="listitem"> 107 BOOST_VMD_SIZE_D 108 </li> 109<li class="listitem"> 110 BOOST_VMD_TO_ARRAY_D 111 </li> 112<li class="listitem"> 113 BOOST_VMD_TO_LIST_D 114 </li> 115<li class="listitem"> 116 BOOST_VMD_TO_SEQ_D 117 </li> 118<li class="listitem"> 119 BOOST_VMD_TO_TUPLE_D 120 </li> 121</ul></div> 122<p> 123 Seqs 124 </p> 125<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "> 126<li class="listitem"> 127 BOOST_VMD_IS_SEQ_D 128 </li> 129<li class="listitem"> 130 BOOST_VMD_ASSERT_IS_SEQ_D 131 </li> 132</ul></div> 133<p> 134 Types 135 </p> 136<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "> 137<li class="listitem"> 138 BOOST_VMD_IS_TYPE_D 139 </li> 140<li class="listitem"> 141 BOOST_VMD_ASSERT_IS_TYPE_D 142 </li> 143</ul></div> 144<p> 145 Other 146 </p> 147<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem"> 148 BOOST_VMD_IS_PARENS_EMPTY_D 149 </li></ul></div> 150</div> 151<table xmlns:rev="http://www.cs.rpi.edu/~gregod/boost/tools/doc/revision" width="100%"><tr> 152<td align="left"></td> 153<td align="right"><div class="copyright-footer">Copyright © 2010-2017 Tropic Software 154 East Inc</div></td> 155</tr></table> 156<hr> 157<div class="spirit-nav"> 158<a accesskey="p" href="vmd_internal_macros.html"><img src="../../../../../doc/src/images/prev.png" alt="Prev"></a><a accesskey="u" href="../index.html"><img src="../../../../../doc/src/images/up.png" alt="Up"></a><a accesskey="h" href="../index.html"><img src="../../../../../doc/src/images/home.png" alt="Home"></a><a accesskey="n" href="vmd_dynamic_typing.html"><img src="../../../../../doc/src/images/next.png" alt="Next"></a> 159</div> 160</body> 161</html> 162
