|
||
<p>If this macro is defined, this library internal code is also optimized to reduce compile-time (not just run-time) overhead associated with checking preconditions. In addition, users can manually program <code class="computeroutput">#ifndef</code> statements in their code using this macro to completely disable compilation of preconditions or use the macros defined in <code class="computeroutput">boost/contract_macro.hpp</code> (recommended only for applications where it is truly necessary to completely remove contract code compilation from production code).</p>
