Study Notes
Cyclomatic Complexity Reduction Techniques
Refactoring Techniques
- Extract Method: Break down long methods into smaller, more manageable pieces, reducing complexity.
- Rename Method: Improve method names to better reflect their purpose, reducing confusion.
- Extract Variable: Replace complex expressions with simpler, more readable variables.
- Simplify Conditional Statements: Reduce nesting and complexity in conditional statements.
Code Reorganization Techniques
- Split Large Functions: Divide large functions into smaller, more focused functions.
- Merge Similar Functions: Combine similar functions to reduce duplication and complexity.
- Reduce Nested Loops: Flatten nested loops to improve readability and reduce complexity.
Design Pattern Techniques
- Apply the Single Responsibility Principle (SRP): Ensure each module or function has a single, well-defined responsibility.
- Use Polymorphism: Replace complex conditional statements with polymorphic behavior.
- Introduce Null Objects: Replace null checks with null objects to simplify code and reduce complexity.
Other Techniques
- Remove Dead Code: Eliminate unused code to reduce complexity and improve maintainability.
- Simplify Data Structures: Use simpler data structures to reduce complexity and improve performance.
- Code Reviews: Regularly review code to identify areas of high complexity and apply reduction techniques.
