Multiparadigm Design of SLE API’s Program Interface Based on Design Pattern

It’s an important way to improve the degree of internationalization of data transferring between ground stations in deep space TT&C by applying the SLE protocol. Meanwhile, the design of SLE API is the most important part in SLE applications development. This paper introduces the encapsulation of SLE API’s interface using of design patterns, describes how to use design patterns in multiparadigm. Moreover, it’s also emphasized on the point that how the Class mechanism in object-oriented paradigm is adapted to procedure-oriented paradigm and call-back function is introduced to applied to Observer pattern in latter paradigm. Through multiparadigm encapsulation, the SLE API can acclimatize to most software development environments.
