<overview>

<p>This metric measures the number of lines of code in a function. This excludes comments and blank lines.</p>

<p>Having too many lines of code in a function is an indication that it can be split into several functions of more manageable size.</p>

</overview>

<recommendation>

<p>Long functions should be examined to see if they can be split into smaller, more cohesive functions.</p>
