摘要
面向对象编程语言的继承机制实现了子类和父类间is-a的关系,子类对象成为一个有效的父类对象,具有了父类对象的功能,实现了继承和扩展父类的目的。但是继承难以在分布式环境中跨网络实现,难以实现异构的分布式对象间的继承,所以在借鉴已有绑定技术的基础上,文章将绑定应用到分布式对象之间,提出了一种新的分布式继承模型:利用分布式对象间的绑定来增强和扩展分布式对象的功能,从而达到一种分布式继承的效果。
Inheritance mechanism of object oriented programming language realizes the isa relationship between child class and parent class;it enables child class to inherit the attributes and methods of its parent class;the object of child class becomes a valid parent class's object and has the functions of its parent class's object,so child class inherits and extends parent class's functions.But inheritance cannot be achieved easily across network's boundary in a distributed environment,and it's difficult to realize the inheritance between heterogeneous distributed objects.Based on the binding technology,a new distributed inheritance model is put forward:by binding other distributed objects,the functions of distributed object is boosted up and extended,thereby the purpose of distributed inheritance is obtained.
