In embedded control systems development, specifications are changed frequently and there is strong constraint of memory. We present an object-oriented analysis and design method based on polymorphism patterns. Polymorphism patterns are standard of method interfaces which are shared by several objects. With this method, a system is constructed with objects which have polymorphism patterns. This system ensures reusability because it easy to replace objects where the specification of the system is changed. Object-oriented technology has several functions, such as instantiation, inheritance and polymorphism, where functions are implemented with both method tables and inheritance hierarchy tables. These mechanisms are needless in the automotive engine control application which execute fixed control flow. Our optimization method eliminates these mechanisms and reduces executable code size. We have applied the techniques to the development of automotive engine control applications.","PeriodicalId":276758,"journal":{"name":"Proceedings.

The foundations of software component technology and the possible and useful kinds of software composition are still an open issue of ongoing research. After a clarification of important issues of component technology and component composition, we present an object-oriented component framework that was developed to serve as the basis for an adaptable software development environment. The framework supports the construction of applications with a direct-manipulation user interface (especially graphic editors) and a code generation back-end. It uses a trading mechanism for component integration at run time, facilitates the separation of component adaptation and component composition, and incorporates an architecture that supports system evolution to a certain degree.","PeriodicalId":276758,"journal":{"name":"Proceedings.

During implementation of an object oriented design, the focus lies on individual classes rather than on groups of interacting classes. But individual classes usually implement only small, cohesive parts of system tasks. Important parts of algorithms behind system tasks are hidden in changing object graphs. This can cause malicious problems during restructuring, testing and documentation of object oriented programs, if there is no systematic approach to these activities. The article describes an architecture model, a tool and their application for rigorous analysis of hybrid, object oriented programs at the abstraction level of object graphs and interactions. Analysis results are intended especially to support incremental development of object oriented programs, dynamic documentation and dynamic testing. Object oriented C++ programs serve as analysis objects.","PeriodicalId":276758,"journal":{"name":"Proceedings. Technology of Object-Oriented Languages and Systems, TOOLS 25 (Cat.

While more and more applications are written an Java, a large number of working C++ implementations for standard tasks still exist.

For example different types of objects in a library system might be \"loanable\" or \"catalogued\". The first part of the paper introduces a distinction between object types and attribute types, showing that there are advantages in treating them as separate constructs of an object oriented programming language. Then generalized attribute types, (e.g. \"synchronized\", \"journalized\", \"protected\") are discussed. It is shown how implementations involving a technique called bracket routines can lead to clearly modeled and cleanly implemented programs. It is then shown how the bracket technique can be effectively used to introduce protection and security concepts into a system. Among the clear advantages of this technique is that it results in better reusability of code.","PeriodicalId":276758,"journal":{"name":"Proceedings.

"self"-conscious objects in Object-Z "自我"意识的物体

In contrast, relatively little attention has been paid to this topic in studies on object oriented specification language semantics. In the context of language semantics, the notion of self poses two problems. Firstly, it involves an awareness by an object of its own identity, and hence a capacity for self referential method invocations. Secondly, the usual reference model for object identity maps object identities to object values. This means that an object's identity is not normally considered to be a part of its value. And so a value for self is not normally in scope. The way that a semantics resolves the scope problem can affect one's ability to use the semantics to reason about an object independently of its environment. The paper motivates the inclusion of a concept of self in object oriented formal specification languages, and shows how this concept can be accommodated within the semantics of Object-Z. We show that a useful consequence of making objects 'self'-aware is that messages between objects can be 'tagged' with the identity of the sender object; this facilitates the task of reasoning about object interaction.","PeriodicalId":276758,"journal":{"name":"Proceedings.

Only under these conditions will the other quality factors advertised for the method, in particular the increase in reusability and extendibility, yield the expected benefits for software practitioners. It is indeed possible to use object-oriented technology to produce, almost routinely, software systems that reach a degree of reliability without any equivalent in conventional methods, languages and tools. This requires a strict application of pure object-oriented concepts, in particular, seamlessness (the use of a consistent method and notation throughout the software life-cycle), information hiding, automatic garbage collection, static typing, and the combination of static typing and dynamic binding. Another key component of this approach is the notion of design by contract, which leads to the production of systems whose correctness is built-in rather than ensured ex post facto.","PeriodicalId":276758,"journal":{"name":"Proceedings.
