TTCN-3数据系统的实现在郌照TTCN-3标准的基础上，还需要支持数据兼容等特性。针对该问题，给出一种TTCN-3数据系统到Java的翻译方案。利用Java语言具有的继承、多态等面向对象的特色，借鉴抽象工厂设计模式，通过检视分析翻译生成代码。证明该方案符合 TTCN-3标准规定，并清晰地体现数据系统中的数据类型和数据值的功能区分。该方案支持不同数据类型的兼容和数据值之间的比较，并易于扩展。%For implementation of data system of TTCN-3, it is a mandatory request to support several features, e.g. type capability, while in accordance with standards of TTCN-3. In order to solve this problem, this paper gives a translation scheme from TTCN-3 into Java, which utilizes Java’s object-oriented natures such as inherence and polymorphism, and refers the abstract factory pattern. To inspect and analyze the outcome code, it is concluded that this scheme makes a clear functional separation of data type and value. Besides, this scheme supports compatibility between different data types and comparison between different data values, and is easy to be extended.
