Research on Source Code Generation Support for Aiding Design Patterns

将设计模式应用于应用程序的设计，可以使应用程序健壮地应对与可扩展性和可维护性相关的问题。然而，目前，设计人员必须手动将设计模式的结构和约束应用于应用程序，因此经常会出现错误。我们提出了一个符号使用SGML描述设计模式和设计模式的支持系统。我们的目标是提供一个基于符号和系统的源代码生成支持系统。利用已有的知识，如基于算法和数据结构的库，以及基于面向对象技术封装的类，半自动应用程序生成器已经有了很多研究。当使用设计模式支持源代码生成时，必须考虑对这种半自动应用程序生成器的相同需求。这些要求是减少用户编写的代码，并满足约束条件，而不引起用户的注意。

Applying design patterns to design of an application makes it robust against issues related to extensibility and maintainability. However, currently, a designer must apply structures and constraints of design patterns to an application by hand, therefore mistakes can occur often. We have proposed a notation using SGML for describing design patterns and a support system for design patterns. We aim at providing a source code generation support system based on the notation and system. There have been many researches on semi-automatic application generators using existing knowledge such as libraries based on algorithms and data structure, and classes packaged based on the object-oriented technology. When using design patterns for source code generation support, the same requirements for such semi-automatic application generators must be considered. The requirements are lessening codes to be written by users, and satisfying constraints without directing users' attention to them.
