The Research And Application Of Software Refracting Based On Interface Extension

With the gradual promotion of 3G applications, the mainstream of software applications has changed from PC to handheld intelligent terminals. The resulting is software platform migration, but the main function doesn't have too much change, only small changes in several modules. The new code for re-application platform will add additional costs, but also hard to ensure that the new software can adapt to the next technological innovation.In order to solve software structural rigidities and poor scalability, people have come up many refracting method such as extracting method, long method segmentation. These methods in solving some project with the small-scale and low modules coupling can play its role well, but the role is very limited when they encounter some large-scale and high modules dependency project.In response to these problems, this paper proposes a software refracting method based on interface extension. This method based on the basic principles of object-oriented, using the interface extraction and encapsulation principle, and it will be an advanced solution for the software project refracting with large-scale and high-coupling. In addition, this method apply for practical projects in this research, and the results of the refracting experiment are verified and analysis.
