摘要

针对面向上下文的编程语言未提供支持动态层添加机制的缺陷

提出了一种以虚拟机为核心的支持层动态添加的编程框架

并给出了实现方法。编程框架的核心是一个扩展后的Java虚拟机将谓词测试融入到Java虚拟机来实现程序对上下文的感知

将对象组合与代理融入到Java虚拟机来实现层的动态激活

利用虚拟机自身提供的功能实现动态层添加。实验结果表明

基于扩展后的Java虚拟机的编程框架可以实现层激活和动态层添加

编程框架的层激活效率较基于编译器的最多提高10%左右。

Abstract

A programming framework is proposed to address the problem that the context-oriented programming languages do not provide any mechanisms to support dynamic layer addition

and its implementation is presented. The key component of the framework is an extended Java virtual machine. It incorporates predicate for checking object composition and delegation to implement layer activation

and uses existing virtual machine services to support dynamic layer addition. Therefore

the framework provides the capabilities of layer activation and dynamic layer addition. Experimental results show that the performance of layer activation in the proposed framework is approximately 10% higher than that in ContextJ.
