<h2><a name="BOOST_PP_LIST_TRANSFORM">#define BOOST_PP_LIST_TRANSFORM</a>(F,P,L)</h2>
|
|
<p>Applies the macro <code>F(D,P,X)</code> to each element <code>X</code>
|
|
of the list producing a new list.</p>
|
|
|
|
<p>In other words, expands to:</p>

<pre>

<a href="list_adt.htm#BOOST_PP_LIST_CONS">BOOST_PP_LIST_CONS</a>(F(D,P,<a href="list_at.htm#BOOST_PP_LIST_AT">BOOST_PP_LIST_AT</a>(L,0)),
|

<a href="list_adt.htm#BOOST_PP_LIST_CONS">BOOST_PP_LIST_CONS</a>(F(D,P,<a href="list_at.htm#BOOST_PP_LIST_AT">BOOST_PP_LIST_AT</a>(L,1)),

|
<a href="list_adt.htm#BOOST_PP_LIST_NIL">BOOST_PP_LIST_NIL</a>) ... ))
|
|
</pre>
|
|
|
|
<p>For example,</p>
|
|
|
|
<pre>
|
|
<a href="list_transform.htm#BOOST_PP_LIST_TRANSFORM">BOOST_PP_LIST_TRANSFORM</a>(BOOST_PP_ADD_D,2,<a href="tuple_to_list.htm#BOOST_PP_TUPLE_TO_LIST">BOOST_PP_TUPLE_TO_LIST</a>(2,(1,2)))
|
|
</pre>
|
|
|
|
<p>expands to the same as:</p>
|
|
|
|
<pre>
|
|
<a href="tuple_to_list.htm#BOOST_PP_TUPLE_TO_LIST">BOOST_PP_TUPLE_TO_LIST</a>(2,(3,4))
