| 中文摘要 | 针对现在手机程序设计语言存在编程效率低,可扩展性差等缺点,提出了一种高效的可扩展脚本语言——PScript。PScript语言以Python语言为原形,建立在J2M E(Java 2 m icro ed ition)平台上,具备开发效率高、支持动态链接、代码可释放、执行的二进制代码小、可读性好、代码清晰、节省运行空间等优点。详细分析了PScript语言的语法与类库,编译器与虚拟机等部分,并阐述了动态载入实现细节。通过和M IDP(m ob ile in form ation dev ice profile),M ob ileB as ic进行常规性能测试,网络动态载入性能测试以及语言特性的对比测试,充分体现出PScript语言编写及运行效率高,可扩展性强的特点。; Several programming languages are used for cellular phone programming,but none are very efficient and extendable.This paper describes a scripting languages,PScript,based on the Python language and running on the J2ME(Java 2 Micro Edition) platform.The method has good extensibility.PScript is an efficient larguage with dynamic loading and unloading support,small binary code size,good readability,and small memory footprint.This paper analyzes the syntax,libraries,compiler,and virtual machine to show the implementation details of the dynamic loading feature.The network dynamic loading performance is compared with that of MIDP(mobile information device profile) and MobileBasic to illustrate PScript's programming productivity,execution performance,and high extensibility.; 国家自然科学基金资助项目(60433040) |
