ded. A histogram which consists entirely of inclusive axes can be filled more efficiently, which can be a factor 2 faster.</p>
<p>An axis with underflow and overflow bins is always inclusive, but an axis may be inclusive under other conditions. The meta-function checks for the method <code class="computeroutput">constexpr static bool inclusive()</code>, and uses the result. If this method is not present, it uses get_options&lt;Axis&gt; and checks whether the underflow and overflow bits are present.</p>
