Cohesion and reuse in an object-oriented system

Abstract

We define and apply two new measures of object-oriented class cohesion to a reasonably large C++ system. We find that most of the classes are quite cohesive, but that the classes that are reused more frequently via inheritance exhibit clearly lower cohesion.

“…An assortment of realized quantities and qualitative ordinal scales have been defined for cohesion and coupling [50,51,52].…”

A model for estimating change propagation in software

“…If there is only one set in a class, COR will result in 1, which indicates a high cohesion. Ferreira et al (2011) carried out an experimental evaluation of four cohesion metrics: LCOM (lack of cohesion in methods) (Chidamber and Kemerer 1994), LCOM4 (Hitz and Montazeri 1995), TCC (tight class cohesion) (Bieman and Kang 1995), and COR. Findings of that work showed that COR may be used as a good indicator of class cohesion and it is useful in identifying classes with design deviance.…”

How Does Refactoring Affect Internal Quality Attributes?: A Multi-Project Study

“…Existing techniques can measure cohesion from different levels of the source code. In the context of our study, we use techniques to measure cohesion in classes (5,39) and are explained in detail in Section 3.5.…”

“…After, we investigated the quality metrics for quantifying each internal quality attribute. We defined a set composed by 25 quality metrics based on previous work (6,30,31,39,42,45,46). To select appropriate metrics per internal quality attribute, we applied the following criteria.…”

“…To select appropriate metrics per internal quality attribute, we applied the following criteria. First, we selected well-known metrics from the literature (6,31,39,45,46), including the CK suite (30) and McCabe's cyclomatic complexity (42). Second, we selected metrics that assess different properties of each internal quality attribute (30,37,47,42).…”
