This paper presents an empirical validation of two inheritance-based metrics: Average Understandability (AU) and Average Modifiability (AM), for the estimation of the modifiability of object-oriented ...

An object constructed from a subclass contains all the fields that the subclass defines, and all the fields that are contained in its superclass (and the superclass of the superclass, etc. all the way ...

Diagram the Ruby method lookup chain, and compare it to the JavaScript prototype lookup chain. Write a class which inherits from another class. In Ruby, we have classes instead of prototypes. We ...

Several metrics have been proposed for the measurement of the inheritance hierarchy of object-oriented software designs. This paper presents an empirical validation of two inheritance-based metrics: ...
