摘要
CAR构件技术是面向构件的编程模型,它兼容微软的COM并对COM进行了扩展。该文分析了COM的不足之处,提出了以CAR_CLSID扩展CLSID的方案,并应用到CAR构件技术之中。CAR_CLSID是对CLSID的扩展,通过CAR_CLSID,客户可以不依赖于系统注册表来创建CAR对象,CAR构件不需要安装和注册即可被客户端使用,而且可以很好地描述构件依赖关系,这些都有力地支持了构件的自描述。该文从以上各个方面深入剖析了CAR_CLSID的机理。
CAR Component technology is component oriented programming model.CAR is compatible with Microsoft's COM and an extention of COM.This article analyzes the lack of COM and brings forward an identifier named CAR_CLSID which is used in CAR component.CAR_CLSID is an extention of CLSID in COM and supports the compo-nent self-describing.It is independent of the operating system to create an object associated with the CAR_CLSID.A CAR component can be used by the client without being installed and registered.And a CAR component can describe the other CAR components it depends on easily by CAR_CLSID.Focusing on these aspects,the article analyzes the mechanism of CAR_CLSID.
