/** <p>Generates a comma separated list of shifted actual parameters.</p>
|
|
|
|
<p>In other words, expands to the sequence:</p>
|
|
|
|
<pre>
|
|
BOOST_PP_CAT(PARAM,1), BOOST_PP_CAT(PARAM,2), ..., BOOST_PP_CAT(PARAM,BOOST_PP_DEC(COUNT))
|
|
</pre>
|
|
<p>For example,</p>
|
|
|
|
<pre>
|
|
BOOST_PP_ENUM_SHIFTED_PARAMS(3,x)
|
|
</pre>
|
|
|
|
<p>expands to:</p>
|
|
|
|
<pre>
|
|
x1, x2
|

</pre>

<h3>Uses</h3>
|
|
<ul>
|
|
<li>BOOST_PP_REPEAT()</li>
|
|
</ul>
|
|
|
|
<h3>Rationale</h3>
|
|
<ul>
|
|
<li>This macro facilitates a typical usage of the library. Shifted parameter
|
|
lists are common in template metaprograms.</li>
|
|
</ul>
|
