<overview>
<p>This metric measures the number of public functions in a file.</p>

<p>Public functions are the API between a component and other parts of a program. As such,
it makes sense to monitor the number of public functions and consider the following
questions:</p>

<ul>
<li>Is the API too large and unwieldy?</li>
<li>When adding new functions, what effect will the new additions have on the cost of
    maintaining the additions (given that other components may come to rely on them)?</li>
<li>Do any public functions inadvertently expose implementation details of a component?</li>
</ul>

</overview>
<recommendation>

<p>Adjust the API of a component in consideration of the above questions.</p>
