As any experienced C++ programmer knows, virtual functions are slower than normal functions because they require more indirection. Each object must have its v-table pointer dereferenced in order to access the v-table itself, and then a table lookup has to be performed to call the actual function...
Good object oriented design recommends theabstractionof the data store from of the application. 好的对象定向设计需要从程序中抽象出数据存储. 期刊摘选 This is a kind ofabstraction. 这是一种抽象物. 期刊摘选 Such an individual becomes a metaphysicalabstraction. ...

We refer to a task as a sequence of object-oriented task steps or skills, each consisting of their own action model and performed in series to achieve a goal. As an example, a cup-pouring task would consist of three action models: (i) grasping the cup, (ii) lifting the cup, and (...

Chidamber and Kemerer [45] proposed six design metrics in object-oriented classes, which later became what is commonly known as the CK metric suite: Weighted Methods Per Class (WMC), Depth of Inheritance Tree (DIT), Number of Children (NOC), Coupling Between Object classes (CBO, also known...
On understanding data abstraction, revisited | Proceedings of the 24th ACM SIGPLAN conference on Object oriented programming systems languages and applications 群里看到 @圆角骑士魔理沙 提到了两篇关于OO好处的经典文章,于是特来阅读。一查才知道作者William R. Cook已经在几年前去世了,他也是我的一位co-adv...
As a developer used to Object Oriented paradigm I was wondering what are the functional equivalents of popular design patterns. One of the best articles summarizing this subject is Mark Seeman’s “Patterns Across Paradigms”. I am currently working on a small project where I had a chance to ...
