Inheritance is the principle that deontic ‘ought’ closed under entailment. This paper about a tension arises in connection with Inheritance. More specifically, it two observations pull opposite directions. One of them raises questions validity Inheritance, while other appears to provide strong support for it. We argue existing approaches modals fail us an adequate resolution this tension. In re...

This is the seventeenth article in a regular series on object-oriented theory for nonspecialists. Using a second-order λ-calculus model, we have previously modelled the notion of inheritance as a short-hand mechanism for defining subclasses by extending superclass definitions. Initially, we considered the inheritance of type [1] and implementation [2] separately, but later combined both of thes...

The inheritance class hierarchy is an important characteristic of object orientation. Many aspects of inheritance mechanisms remain controversial. Among others, many questions about the necessity of multiple inheritance have been put forward. Another contribution is given to this question by our experimental study. Dvorak [1994] revealed the phenomenon of conceptual entropy in class hierarchies...

Inheritance is one of the key issues of object-orientation. The inheritance mechanism allows for the definition of a subclass which inherits the features of a specific superclass. This means that methods and attributes defined for the superclass, are also available for objects of the subclass. Existing methods for object-oriented modeling and design, abstract from the dynamic behavior of object...

Multiple inheritance is a difficult and complex feature added to C# at release 2.0. Cargill argues that the addition was a step backward in that the feature adds complexity to the language without adding functionality. His basis for the latter half of this claim is that no example of multiple inheritance has been given which cannot be rewritten into a functionally equivalent example which uses ...

BACKGROUND The mechanism that initiates the onset of puberty is largely unknown but the age of onset is mainly under genetic control and influenced by environmental factors including nutrition. Familial forms of constitutional delay of puberty (CDP) suggest the involvement of genetic factors. The purpose of this study is to describe the presentation and the mode of inheritance of CDP in a serie...

In this paper, we describe an empirical investigation into the modiiability and understandability of Object-Oriented (OO) software. A controlled experiment was conducted to establish the eeects of varying levels of inheritance on understandability and modiiability. The software used in this experiment consisted of a C++ system without any inheritance and a corresponding version containing three...

This is the sixteenth article in a regular series on object-oriented type theory for nonspecialists. Earlier articles have built up λ-calculus models of objects [1], classes [2], inheritance [3, 4] and generic template types [5]. Classification describes the way in which typed objects fit into a hierarchy of classes, which nest inside each other [3]. Inheritance is the short-hand mechanism for ...
