Application of the Observer Mode in Abstract-Oriented Programming
LIU Lingyun
Abstract：In order to improve scalability and maintainability os software system ,a system framework must be able to build to adapt to the changing needs of the user is system design ,therefore ,in dealing with one to many dependencies in the system ,abstract oriented way of thinking is used ,the observer mode is introduced ,the change part is separated from un-change part ,an abstract class or interface is formed ,so that when an user needs change ,an abstract class or interface imple-mentation class is added without changing the original code ,thereby the robustness of the system is improved greatly the cost of software maintenance is reduced .Practice has proved that in project design ,which layer is abstracted specifically can com-bine various development platforms and make adjustments and optimization ,it is not immutable .
