As a result, I decreased the <a href="https://en.wikipedia.org/wiki/Cyclomatic_complexity">cyclomatic complexity</a> from 24 to 0 and reduced development time from hours to minutes.</p> <p>The rest of this post is organized as follows sections:</p> <ul> <li><a href="#the-problem"><strong>The problem</strong></a> explains the problem I was solving.</li> <li><a href="#creating-the-bit-mask-field"><strong>Creating the bit mask field</strong></a> presents a solution to the problem.</li> <li><a href="#cyclomatic-complexity"><strong>Cyclomatic Complexity</strong></a> discusses cyclomatic complexity and calculates this metric for the solution presented in the section above.</li> <li><a href="#builder-design-pattern"><strong>Builder design pattern</strong></a> explains the builder design pattern and describes the refactoring process that removed complexity.</li> <li><a href="#conclusion"><strong>Conclusion</strong></a> summarizes this post.</li> <li><a href="#references"><strong>References</strong></a> provides references related to the topics discussed here.</li> </ul> <p>All the examples shown here are in C++.</p>
