<p>This function template creates and returns an <code class="computeroutput"><code class="computeroutput"><a class="link" href="overloaded_function.html" title="Class template overloaded_function">overloaded_function</a></code></code> object that overloads all the specified functions <code class="computeroutput">f1</code>, <code class="computeroutput">f2</code>, etc.</p>
|
||||
<p>The function types are internally determined from the template parameter types so they do not need to be explicitly specified. Therefore, this function template usually has a more concise syntax when compared with <code class="computeroutput"><code class="computeroutput"><a class="link" href="overloaded_function.html" title="Class template overloaded_function">overloaded_function</a></code></code>. This is especially useful when the explicit type of the returned <code class="computeroutput"><code class="computeroutput"><a class="link" href="overloaded_function.html" title="Class template overloaded_function">overloaded_function</a></code></code> object does not need to be known (e.g., when used with Boost.Typeof's <code class="computeroutput">BOOST_AUTO</code>, C++11 <code class="computeroutput">auto</code>, or when the overloaded function object is handled using a function template parameter, see the <a class="link" href="../boost_functional_overloadedfunction/Tutorial.html" title="Tutorial">Tutorial</a> section).</p>
|
||||
<p>The maximum number of functions to overload is given by the <code class="computeroutput"><code class="computeroutput"><a class="link" href="../BOOST_FUNCTIONAL_OVERLOADED_FUNCTION_CONFIG_OVERLOAD_MAX.html" title="Macro BOOST_FUNCTIONAL_OVERLOADED_FUNCTION_CONFIG_OVERLOAD_MAX">BOOST_FUNCTIONAL_OVERLOADED_FUNCTION_CONFIG_OVERLOAD_MAX</a></code></code> configuration macro.</p>
