Object-oriented programming in C# with dynamic classification.

Object-oriented programming language has gained popularity in recent years. However, some problems exist in object-oriented programming languages. It works well with static classification, but does not support object dynamic classification. Static classification means an object always and only belongs to one class during its life spans. In real-world applications, objects may belong to different classes rendering different roles certain times during the lifetime. Dynamic classification enables the changing of object classification over time. Objects can be classified and declassified into/from acquire and release class membership during runtime. In this thesis, many approaches to dynamic classification will be discussed in different implementing languages. Based on the thorough reviews of these approaches, we give a new approach. This approach combines the concept of object and roles and extends a class hierarchy with dynamic classification. The syntax of dynamic classification shows how to implement the function of dynamic classification in the object-oriented programming language. Finally, we present a preprocessor, by which a C♯ code including the extendable dynamic classification functions can be translated to standard C♯ code.Dept. of Computer Science.

A general framework for positioning, evaluating and selecting the new generation of development tools.

This paper focuses on the evaluation and positioning of a new generation of development tools containing subtools (report generators, browsers, debuggers, GUI-builders, ...) and programming languages that are designed to work together and have a common graphical user interface and are therefore called environments. Several trends in IT have led to a pluriform range of developments tools that can be classified in numerous categories. Examples are: object-oriented tools, GUI-tools, upper- and lower CASE-tools, client/server tools and 4GL environments. This classification does not sufficiently cover the tools subject in this paper for the simple reason that only one criterion is used to distinguish them. Modern visual development environments often fit in several categories because to a certain extent, several criteria can be applied to evaluate them. In this study, we will offer a broad classification scheme with which tools can be positioned and which can be refined through further research.

Steps Towards a Method for the Formal Modeling of Dynamic Objects

Fragments of a method to formally specify object-oriented models of a universe of discourse are presented. The task of finding such models is divided into three subtasks, object classification, event specification, and the specification of the life cycle of an object. Each of these subtasks is further subdivided, and for each of the subtasks heuristics are given that can aid the analyst in deciding how to represent a particular aspect of the real world. The main sources of inspiration are Jackson System Development, algebraic specification of data- and object types, and algebraic specification of processes
