0243284Atanas RadenskiChapman UniversityThis project will make contributions to the area of component and object oriented languages and programming. The goal is to design, implement, and evaluate class overriding - a new code adaptation language mechanism that is intended to overcome the subclassing anomaly in evolving software components. An in-depth analysis of the subclassing anomaly will reveal and systematize its linguistic roots as found in compiled object-oriented languages. Class overriding will be designed to serve as a generic, language-independent method for anomaly-free component adaptation. Translation patterns for class overriding will define an implementation model with low run-time overhead.This project is expected to have impact on the language design community and on the software architecture community. For the language design community, class overriding will be a linguistic mechanism that can be adapted to either new component-oriented languages, or to existing object-oriented languages, in order to enhance software component adaptability. The software architecture community will be able to employ the analysis of the subclassing anomaly to foresee and avoid possible adaptation anomalies in evolving object-oriented software components.

0243284 Atanas Radenski Chapman University该项目将对组件和面向对象语言和编程领域做出贡献。我们的目标是设计，实现和评估类覆盖-一种新的代码自适应语言机制，旨在克服子类化的异常，在不断发展的软件组件。对子类化异常的深入分析将揭示并系统化其在编译的面向对象语言中的语言根源。类重写将被设计成一种通用的、独立于语言的方法，用于无异常的组件适配。类重写的翻译模式将定义一个低运行时开销的实现模型。该项目预计将对语言设计社区和软件体系结构社区产生影响。对于语言设计社区，类覆盖将是一种语言机制，可以适应新的面向组件的语言，或现有的面向对象的语言，以提高软件组件的适应性。软件体系结构社区将能够采用子类异常的分析，以预见和避免可能的适应异常，在不断发展的面向对象的软件组件。
