【摘要】 提出了一种面向上下文的编程模型IPM(Isotope Programming Model)并介绍了IPM的实施.IPM对已有的面向对象模型进行扩展,引入了新的语言元素,将上下文感知应用的编程对程序员简化,使其只关心程序的逻辑,而不用关心上下文数据的变化.将IPM与现有的面向对象的编程方法进行对比,体现了IPM在上下文感知应用开发中的优越性.更多还原

【Abstract】 The paper proposes a context-oriented programming model which is named Isotope Programming Model(IPM).The paper also discusses the implementation of IPM.IPM extends the object-oriented programming model and introduces new language elements,which simplifies the development of context-aware application and makes programmer only care about the logic of programming and free from the change of context data.The paper also compares the IPM with object-oriented programming model and embodies the advantages of IPM in the fields of the development of context-aware application.更多还原
