|
||
|
|
<p>This macro is used to achieve portable optimal move constructors.</p>
|
||
|
|
<p>When implementing the move constructor, in C++03 compilers the moved-from argument must be cast to the base type before calling <code class="computeroutput">boost::move()</code> due to rvalue reference limitations.</p>
|
||
|
|
<p>In C++11 compilers the cast from a rvalue reference of a derived type to a rvalue reference of a base type is implicit. </p>
