Unit Size

The distribution of size of units (measured in lines of code).

Intro
  • Unit size measurements show the distribution of size of units of code (methods, functions...).
  • Units are classified in four categories based on their size (lines of code): 1-20 (small units), 20-50 (medium size units), 51-100 (long units), 101+ (very long units).
  • You should aim at keeping units small (< 20 lines). Long units may become "bloaters", code that have increased to such gargantuan proportions that they are hard to work with.

  • There are 283 units with 4,992 lines of code in units (60.8% of code).
    • 6 very long units (867 lines of code)
    • 20 long units (1,326 lines of code)
    • 45 medium size units (1,391 lines of code)
    • 49 small units (736 lines of code)
    • 163 very small units (672 lines of code)
