<h4>Lists</h4>
|
|
|
|
|
|
<div>
|
|
|
|
|
|
A <i>list</i> is a simple cons-style list with a head and a tail.
|
|
|
|
|
|
The head of a <i>list</i> is an element,
|
|
|
|
|
|
and the tail is either another <i>list</i> or <b>BOOST_PP_NIL</b>.
|
|
|
|
|
|
For example,
|
|
|
|
|
|
</div>
|
|
|
|
|
|
<div class="code">
|
|
|
|
|
|
(<i>a</i>, (<i>b</i>, (<i>c</i>, <b>BOOST_PP_NIL</b>)))
|
|
|
|
|
|
</div>
|
|
|
|
|
|
<div>
|
|
|
|
|
|
...is a <i>list</i> of <i>3</i> elements--<i>a</i>, <i>b</i>, and <i>c</i>.
|
|
|
|
|
|
</div>
|
|
|
|
|
|
<div>
|
|
|
|
|
|
This allows macro parameters to be variable in size and allows data states to change
|
|
|
|
|
|
size without the user explicitly keeping track of the size independently.
|
|
|
|
|
|
</div>
|
|
|
|
|
|
<div>
|
|
|
|
|
|
Elements of a <i>list</i> can be extracted with
|
|
|
|
|
|
<b>BOOST_PP_LIST_FIRST</b> and <b>BOOST_PP_LIST_REST</b>.
|
|
|
|
|
|
</div>
|
|
