Code Inspection: Complex function should be refactored

Reports the functions or methods that are too complex.

Complexity is evaluated based on four metrics:

  • Lines of code — the number of code lines in a function/method (less is better)

  • Maximum Nesting depth — the maximum number of nested statements in a function/method body (less is better)

  • Cyclomatic complexity — the function/method cyclomatic complexity (less is better)

  • Number of variables — the number of variables used in function/method body

Suppress an inspection in the editor

  1. Position the caret at the highlighted line and press Alt+Enter or click the Intention action icon.

  2. Click the arrow next to the inspection you want to suppress and select the necessary suppress action.
