摘要

耦合是面向对象(OO)研究界研究得很好的一个话题，它对类内聚的影响也很好理解。本文采用扇入和扇出两个耦合度量，对方法调用对类内聚的影响进行了实证研究。三个Java，开源系统(OSS)被用作研究的基础。研究发现，绝大多数扇入和扇出都是由少数类别造成的。我们还发现扇出对班级凝聚力的影响高于扇入。包含扇出的类往往比包含扇入的类具有更低的内聚性。

An Empirical Study of Fan-In and Fan-Out in Java OSS

Coupling is a well researched topic in the Object-Oriented (OO) research community and its influence on class cohesion is well understood. In this paper, we present an empirical study exploring the effect of method calling on class cohesion using two coupling metrics, namely fan-in and fan-out. Three Java, open-source systems (OSS) were used as a basis of the study. A small number of classes were found to account for the vast majority of fan-in and fan-out. We also found the impact of fan-out on class cohesion to be higher than that of fan-in. Classes containing fan-out tended to have lower cohesion than those containing fan-in.
