Hello. I&#39;m trying to build a library and I&#39;m doing heavy use of boost mpl and fusion libraries. I&#39;d like to know a way to fill a boost::fusion::vector&lt;&gt; <br>with the types contained in a boost::mpl::vector. Anyone knows how to do this? The code I have so far:
<br><br>template &lt;class T1, class T2, class T3, class T4, class T5, class T6, class T7, class T8, class T9, class T10&gt;<br>struct Func {<br><br>&nbsp;&nbsp;&nbsp; //This is the initial sequence<br>&nbsp;&nbsp;&nbsp; typedef typename boost::mpl::vector&lt;T1, T2, T3, T4, T5, T6, T7, T8, T9, T10&gt; sequence;
<br><br>&nbsp;&nbsp; //The sequence without NullTypes<br>&nbsp;&nbsp;&nbsp; typedef typename boost::mpl::filter_view&lt;sequence, boost::mpl::not_&lt;boost::is_same&lt;NullType, boost::mpl::_1&gt; &gt; &gt;::type validsequence;<br><br>&nbsp;&nbsp;&nbsp; //The vector I want to fill with validsequence. Note that this is a fusion vector, not a mpl vector
<br>&nbsp;&nbsp;&nbsp; typedef boost::fusion::vector&lt;&gt; voidvector;<br><br><br>&nbsp;&nbsp;&nbsp; /***************PROBLEM HERE*******************/<br>&nbsp;&nbsp;&nbsp; //I want to copy validsequence types into voidvector <br>&nbsp;&nbsp;&nbsp; typedef typename somewaytocopy::type type;
<br>};<br><br><br><br>Thanks in advance.<br>
