The variadic class interface accepts <code class="computeroutput"><span class="number">0</span></code>
|
||
to <code class="computeroutput"><span class="identifier">FUSION_MAX_SET_SIZE</span></code>
|
||
elements, where <code class="computeroutput"><span class="identifier">FUSION_MAX_SET_SIZE</span></code>
|
||
is a user definable predefined maximum that defaults to <code class="computeroutput"><span class="number">10</span></code>.
|
||
Example:
|
||
</p>
|
||
<pre class="programlisting">
|
||
<span class="identifier">set</span><span class="special"><</span><span class="keyword">int</span><span class="special">,</span> <span class="keyword">char</span><span class="special">,</span> <span class="keyword">double</span><span class="special">></span>
|

</pre>
|
||
<p>
|
||
You may define the preprocessor constant <code class="computeroutput"><span class="identifier">FUSION_MAX_SET_SIZE</span></code>
|

before including any Fusion header to change the default. Example:

</p>
|
